Your company produces a sunblock lotion designed to protect the skin from both UVA and UVB exposure from the sun. You hire a company to compare your product with the product sold by your major competitor. Let's suppose that the true percent of the time that your lotion would perform better is $p_{0}=0.65$ and you plan to test the null hypothesis $H_{0}: p_{0}=0.5$ versus the two-sided alternative $H_{a} : p_{0} \neq 0.5$ at the $5 \ %$ level. You have a budget that will allow you to test 120 subjects. Use software to find the power of the test for this value of $n$. (Use decimal notation. Give your answer to two decimal places.) power:

Since the pandemic, the price of gasoline varies constantly from the last two months. However, youobserved that local gas stations charge higher price. You want to test your hypothesis that local gas stations are charging much more than the national average price for What is your claim about this problem? What is the null hypothesis of this study?
A clinical trial is run to investigate the effectiveness of an experimental drug in reducing high blood pressure in women to a drug considered standard care and to placebo. Women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or placebo. Women are followed through for (< 37 weeks) or not. The data are shown below. Is there a statistically significant difference in the proportions of women having high blood pressure among the three treatment groups? Run the test at a 5% level of significance. Appropriate test? Decision Rule? Test Statistic? Yes No Total Experimental Drug 7 33 40 Standard Drug 13 32 45 Placebo 17 18 35 Total 37 83 120
A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function: Y= 15.50 + 0..90B+1.15A. (0.55) (0 40) The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will ▼ the null hypothesis. Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure. So, the test statistic associated with the one-sided test the…

Dr. Watts is a pediatrician. His group did some research on the sleep habits of children less than 24 months old. They found a weak negative correlation between a child’s age and the number of hours per day he or she slept. What does this mean? As a child’s age increases, the hours of sleep decreases in a nearly perfect pattern. As a child’s age increases, the hours of sleep increases in a nearly perfect pattern. As a child’s age increases, the hours of sleep decreases but the relationship is not perfect. As a child’s age increases, the hours of sleep increases but the relationship is not perfect.
In 'Stat' World it is known that 10% of the entire population of 100 million people are infected with 'HALO' disease. 'HALO' has a range of outcomes that range from 'asthma' to 'reduced life span' to 'imminent death'. 'Stat World' has developed a screening to test for the 'HALO', and this test has an accuracy of 80% in identifying 'HALO'. 'Stat World' has also developed a 'HALO' treatment ('BLOCK') that has 90% rate of full cure if you have 'HALO'. However if you receive 'BLOCK' treatment and do not have 'HALO' disease you will be incurably infected with 'HALO'. What is the probability that you have 'HALO' if you test positive for 'HALO'? What is the probability that you have 'HALO' if you test negative for 'HALO'? What is the probability that you are harmed by 'BLOCK' treatment if you tested positive for 'HALO'? What is percentage of population that will be cured by 'BLOCK' if all positive 'HALO test results are treated with 'BLOCK'? (e) What is percentage of…
A man had a height that is at the 99.725th percentile of the distribution for height. This means that his height is approximately _ SD(s) above the average. Using regression, we can predict that his weight will be approximately _ SD(s) above average. Therefore, he is predicted to have a weight at the _ percentile of the distribution for weight.

The federal government recently granted funds for a special program designed to reduce crime in high-crime areas. A study of the results of the program in high-crime areas of Miami, Florida, are being examined to test the effectiveness of the program. The difference in crimes reported is calculated as (crimes after - crimes before). You want to test whether the average number of crimes reported after are different from the average number of crimes reported before. What are the hypotheses for this test?

Photon is a training device that is designed to improve a user's reaction time. Similar devices have been criticized for being too easy to master, but the makers of Photon say that their device is built to give most users room to improve. The makers say that even among professional athletes, the proportion, , who can score the top ranking of "light speed" is less than 16%. A random sample of 110 professional athletes is chosen, and 14 score a ranking of "light speed" while using the device.Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the level of significance, to support the claim that the proportion of all professional athletes who can score a ranking of "light speed" is less than 16% .
