Over the course of his career, his overall made free-throw percentage was 53.3%. During one off-season, Shaq had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shaq made 26 of 39 free- throw attempts. Test the claim that Shaq has significantly improved his free-throw shooting using a 0.05 significance level. Do you retain or reject the null hypothesis? Retain the null.…

A survey of 200 middle managers showed a distribution of the number of hours of exercise they participated in per week with a mean of 3.64 hours and a standard deviation of 4.76 hours. Complete parts (a) through (c) below. Question content area bottom Part 1 a) According to the Normal model, what percent of managers will exercise fewer than one standard deviation below the mean number of hours? (Round to the nearest whole number as needed.) Part 2 b) For these data, what does that mean? Explain. Select the correct choice below and fill in the answer box(es) within your choice. (Type integers or decimals.) A. One standard deviation below the mean is enter your response here hours. This means that enter your response here% of managers are exercising no more than this number of hours. B. One standard deviation below the mean is enter your response here hours.

Do wearable devices that monitor diet and physical activity help people lose weight? Researchers had 237 subjects, already involved in a program of diet and exercise, use wearable technology for 24 months. They measured their weight (in kilograms) before using the technology and 24 months after using the technology. (a) Explain why the proper procedure to compare the mean weight before using the wearable technology and 24 months after using the wearable technology is a matched pairs t test. Choose the correct explanation. A person's weight before and after wearing the device would not be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test. O A person's weight before and after wearing the device would be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test.

I need help with stats/2023, section 6.2 (please help with TI-84 commands please) Thanks Use the standard normal distribution or the t-distribution to construct a 95% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a recent season, the population standard deviation of the yards per carry for all running backs was 1.27. The yards per carry of 25 randomly selected running backs are shown below. Assume the yards per carry are normally distributed. 2.4 5.4 5.9 4.6 3.5 4.9 4.9 6.8 3.2 1.3 2.6 4.1 5.2 7.3 3.5 4.1 2.8 4.9 3.8 6.4 5.6 4.4 ..........................6.9 6.5 3.8 Which distribution should be used to construct the confidence interval?
