Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma.† Over a period of months, an adult male patient has taken nine blood tests for uric acid. The mean concentration was x = 5.33 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with ? = 1.79 mg/dl. (a)Find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (Round your answers to two decimal places.) lower limit=__ upper limit=__ margin of error=__ (b)What conditions are necessary for your calculations? (Select all that apply.) A-? is known B-? is unknown C-uniform distribution of uric acid D-n is large E-normal distribution of uric acid c)Interpret your results in the context of this problem. MULTIPLE CHOICE A-We are 5% confident that the true uric acid level for this patient falls within this interval.…

Suppose we want to test the hypothesis that mothers with low socioeconomic status (SES) deliver babies whose birth weights are different from normal. To test this hypothesis, a random sample of 100 birth weights is selected from a list of full-term babies of SES mothers. The mean birth weight is found to be 115 oz. Suppose the average birth weight of all babies (based on nationwide surveys of millions of deliveries) is known to be 120 oz with = 24 oz. Set = .05 Assume all conditions are met, what is the p-value of their test? Give your answer to 4 decimal places.

Albumin is a liver protein that helps with circulation of hormones, vitamins, and enzymes throughout our body. Reduced albumin concentrations have been associated with severe liness among individuals infected with COVID-19. Suppose we wanted to conduct a study to compare the mean Albumin concentration (gL) between a sample of adult patients hospitalized at MUSC for COVID-19 infection (g=32.8, s-6.0) to the mean Albumin concentration (gL) of healthy U.S. adults (u-34.1, os7.13). How many patients would we need to enroll from MUSC to conduct this study with 95% confidence, and 90% power? From: Chen T, Wu D, Chen H, et al.

A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean monthly mileage, µ, of car rented in the U.S. this year. The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is different from last year’s mean, which was 2700 miles. The group plans to do a statistical test regarding the value of µ. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2565 miles and the standard deviation to be 800 miles. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: µ is ____ __? __ H1: µ is ____ __ ? ___ In the context of this test, what is a Type II error? A Type II error is ?________ ___ the hypothesis that µ is ? _____ ? when, in fact, µ is ? ____ Suppose that the group decided to reject the null…
