This question asks you to extend the medical-test example from class. Suppose there is a medicalcondition that afflicts 20% of the population. There is a test for this condition, and the reliabilityof this test can be characterized as follows:false-positive rate = 10%- for those who do not have the condition, 10% willtest positive.• false-negative rate 5%- for those who have the condition, 5% will test neg-%3Dative,(a) If you receive a positive test result, what is the likelihood that you have the condition?If you receive a negative test result, what is the likelihood that you do not have the condition?(b) Repeat part (a), except now assume that the false-positive rate is 5% and the false-negativerate is 10%,

If the attachment picture answer is correct (if not, what is the answer & how did you get the answer) In the Invisible Gorilla experiment, the assumption is that most observers in this experiment would notice a person in a Gorilla suit walk into the middle of the ball tossers, beat their chest, and walk out. In our hypothetical example, H0 = The relative frequency of successes in the population is p = 0.75 (ie, most observers) HA = The relative frequency of success in the population is something other than p = 0.75 (p ≠ 0.75) In looking at your calculated 95% confidence interval (assuming your answer is correct), does the value of 0.75 fall inside or outside of the interval? Would you then reject or fail to reject the null hypothesis? (select all that applies) inside outside reject fail to reject
Pele took all samples of size n=40 from a population of test scores. He found that on average, the sample means he obtained were 6.2 points away from the mean of the sample mean which was 80. What are the standard error and the expected value of Pele’s dataset?
You are playing a dice game with a friend and become suspicious that he is using weighted dice. So you stop the game, take one of his dice, and roll it 100 times. The results are in the table below. Do these results provide significant evidence that the proportion of times the dice lands on the six numbers are unequal? Calculate the chi-squared test statistic and the range the p-value falls in for this test. Number on die 1 2 4 Frequency 16 21 6 26 13 18 test statistic = 14.12, p-value in (.01, .025) test statistic = 24.368, p-value in (.005, .01) test statistic = 14.12, p-value in (.025, 05) test statistic = 24.368, p-value less than .005 O none of these
How many false negative were there? Explain the meaning of a false negative for the person tested.
A survey by Men’s Health magazine stated that 14% of men said they used exercise to reduce stress. Could this be valid, or is it actually less than what the magazine claims? A random sample of 100 men was selected, and 10 said that they used exercise to relieve stress. If a=0.10, test a hypothesis and state your conclusion in context.
Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher wants to know if people find baby animals cuter than adult animals. All of the participants in a study are shown 10 pictures of baby animals and 10 pictures of adult animals. They are asked to rate (on a 1 to 10 scale) how cute they think each animal is.
If a treatment is expected to increase scores on a variable for which the mean is expected to be µ = 100, what is the null hypothesis? µwith treatment > 100 µwith treatment < 100 µwith treatment > 100 µwith treatment < 100
An occurrence sampling study of students in the classrooms concluded that 40% of the students wear shorts to class in May. What is the range of values within which you feel the true percentage lies if (a) absolute accuracy is 10% and (b) relative accuracy is 10%?
For example before the pandemic, students from the 7:00am class reported that they sleep on average 6 hours. However, report shows that it is uncertain whether students sleep longer than six hours or less than 6 hours. Someone consulted you on how to provide statistical evidence whether the students sleep less than 6 hours or more than 6 hours. what test will you use to investigate the problem above?

You want to study whether music affects people’s ability to learn. You have 10 college students study a list of words with soft classical music playing, then you test how many words they correctly remember. You happen to know that on this particular type of memory test, the population can correctly remember a mean of μ = 7.2 words with a standard deviation of σ = 2.2 words. What kind of hypothesis test should you do? Group of answer choices One-Sample t-test Independent-Samples t-test Related-Samples t-test One-Sample z-test
The probability of a given score range is 0.4821. The bottom of the score range is the average (z=0). What is the z-score for the upper end of the distribution?
