Find the 75 percentile score for the psychological test. d.

Answers

Answer 1

The 75th percentile score for the psychological test is 22.348 minutes.

We need to find the mid 99.7% quiz completion test ranges and the percentage of patients who will complete the test in more than 22 minutes. Then, we need to determine the range of time for the mid 95% of the patients and the 75th percentile score for the psychological test.

To find the mid 99.7% quiz completion test ranges, we will use the 68-95-99.7 Empirical rule. According to this rule, for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% of the data falls within two standard deviations of the mean, and 99.7% of the data falls within three standard deviations of the mean.

Therefore, we can calculate the mid 99.7% quiz completion test ranges by adding and subtracting three standard deviations from the mean.

The mean is given as 21 minutes, and the standard deviation is given as 2 minutes. So, the mid 99.7% quiz completion test ranges are 21 ± 3(2) minutes, which gives a range of 15 to 27 minutes.

To find the percentage of patients who will complete the test in more than 22 minutes, we need to calculate the z-score for 22 minutes. The formula for calculating the z-score is (x - μ) / σ, where x is the value we want to find the z-score for, μ is the mean, and σ is the standard deviation.

So, the z-score for 22 minutes is (22 - 21) / 2 = 0.5. From the standard normal distribution table, we can see that the percentage of patients who will complete the test in more than 22 minutes is approximately 30.85%.

To determine the range of time for the mid 95% of the patients, we can use the same empirical rule. The mid 95% of the patients means that the remaining 5% of the data is split between both tails of the distribution. Since the distribution is symmetric, each tail will contain 2.5% of the data. Therefore, we need to find the z-scores that correspond to the 2.5th and 97.5th percentiles of the distribution.

From the standard normal distribution table, we can find that the z-score for the 2.5th percentile is -1.96, and the z-score for the 97.5th percentile is 1.96. Using these z-scores, we can calculate the range of time for the mid 95% of the patients as follows:

Lower range = μ - 1.96σ = 21 - 1.96(2) = 17.08 minutes

Upper range = μ + 1.96σ = 21 + 1.96(2) = 24.92 minutes

To find the 75th percentile score for the psychological test, we can use the z-score formula again. We need to find the z-score that corresponds to the 75th percentile, which is equivalent to saying we need to find the score below which 75% of the data falls. From the standard normal distribution table, we can find that the z-score for the 75th percentile is approximately 0.674.

Using the z-score formula, we can solve for the value of x as follows:

0.674 = (x - 21) / 2

x - 21 = 1.348

x = 22.348 minutes

Therefore, the 75th percentile score for the psychological test is 22.348 minutes.

The cemetery has over 200 graves, with all sexes and ages represented in the skeletal sample. You are interested in knowing whether there were gender differences in health among members of the medieval community. How would you answer this question using the skeletal remains

Answers

Answer:

By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)

Explanation:

Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.

The risk of getting lung cancer at some point in time in one's life for men who have never smoked is about 13 in 1000. The risk for men who smoke is just over 13 times the risk for non-smokers. What is the approximate lifetime risk of getting lung cancer for men who smoke

Answers

0.169  is the approximate lifetime risk of getting lung cancer for men who smoke.

In the United States, about 10 to 20% of lung cancer cases, or 20,000 to 40,000 lung cancers each year, occur in people who have never smoked or have smoked fewer than 100 cigarettes in their lifetime.

In this case, if we talk about the risk of smokers in terms of the risk of non-smokers, so the baseline risk is the risk for the non-smokers. So the baseline risk for lung cancer in men over an entire lifetime is the risk of lung cancer for men who have never smoked, over their lifetime, which is =0.013

The approximate lifetime risk of getting ling cancer, for male smokers, can be calculated as being 13 times the base risk= 0.169

The two types of information processing that take place in the brain are the type that takes place when a stimulus exceeds a specific threshold of significance and enters conscious awareness. There are billions of neurons in our brains. To carry out certain cognitive functions, like as idea production or movement control, billions of neurons fire.

The peak of these collective electrical signals corresponds to a high in brain activity, and the dip corresponds to a dip in neural activity, much like a wave. It has been speculated that frontal cortex and the extrastriate play a significant role in the expression of conscious awareness.
