**Text Transcription:**A medical researcher treats 400 subjects with high cholesterol using a new drug. After two months of taking the drug, the average decrease in cholesterol level is $ \bar{x} = 75 $, and the researcher assumes that the decrease in cholesterol follows a normal distribution, with unknown mean $ \mu $ and standard deviation $ \sigma = 15 $. Construct a 99% confidence interval for $ \mu $.**Explanation:**This handwritten text provides information about a medical study involving a new drug for high cholesterol. It details a statistical problem where the researcher needs to construct a confidence interval for the mean decrease in cholesterol level. - **Sample size**: 400 subjects- **Sample mean $(\bar{x})$**: 75- **Standard deviation $(\sigma)$**: 15- **Confidence level**: 99%The task is to find the 99% confidence interval for the population mean ($\mu$) of the decrease in cholesterol. The information implies using the normal distribution to carry out this statistical analysis.

Given that the researcher wants to be sure the mean difference in the change in hemoglobin levels has a margin of error no more than 0.2 g/dL and the difference in the stand deviation between the mean hemoglobin levels for the two forms of iron supplements used to treat anemia is 1.2 g/dL, what is the desired number of recruits for the study, assuming the individuals will participate in a crossover trial, if the study’s attrition rate is expected to be .25? Group of answer choices n = 139 n = 554 n = 185 n = 55,320
Does the average Presbyterian donate less than the average Catholic in church on Sundays? The 58 randomly observed members of the Presbyterian church donated an average of $24 with a standard deviation of $15. The 42 randomly observed members of the Catholic church donated an average of $31 with a standard deviation of $7. What can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer t-test for the difference between two dependent population means z-test for a population proportion t-test for a population mean t-test for the difference between two independent population means z-test for the difference between two population proportions The null and alternative hypotheses would be: H0:H0: Select an answer p1 μ1 Select an answer ≠ > = < Select an answer p2 μ2 (please enter a decimal) H1:H1: Select an answer p1 μ1 Select an answer < = ≠ > Select an answer p2 μ2 (Please enter a decimal) The test statistic ?…

in a test of the effectiveness of garlic for lowering cholesterol, 43 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes in their levels of LDL cholesterol have a mean of 5.7 and a standard deviation of 17.7. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic and reducing LDL cholesterol?
Do shoppers at the mall spend more money on average the day after Thanksgiving compared to the day after Christmas? The 52 randomly surveyed shoppers on the day after Thanksgiving spent an average of $122. Their standard deviation was $29. The 59 randomly surveyed shoppers on the day after Christmas spent an average of $117. Their standard deviation was $35. What can be concluded at the αα = 0.05 level of significance?

A study wanted to compare the weight loss between two drugs. They sampled 60 people. 30 who took drug A and 30 who took drug B. With drug A the average weight loss was 15 pounds with a standard deviation of 8 pounds. With drug B the average weight loss was 18 pounds with a standard deviation of 9 pounds. Approximate the difference in weight loss (drug A - drug B). Enter the lower limit of a 90% confidence interval. (Rond to the nearest tenth).
