The anterior cruciate ligament (ACL) runs diagonally in the middle of the knee. An articlereported results for 85 young athletes who suffered anterior cruciate ligament (ACL) injuries.Of the 80 injuries, 45 were to the left knee and 35 were to the right knee. In testing if morethan half of ACL injuries are to the left knee, the p-value for testing the null hypothesisp = 0.50 versus the alternative hypothesis p > 0.50 is(A) 0.263(C) 0.131(B) 0.035(D) 0.868

What is the value of the test statistic for a test with a null hypothesis that mu = 100, Xbar = 110, the standard error = 20 and n = 49?
The average number of calories from a fast food meal for adults in the US is 842 calories. A nutritionist believes that the average is higher than reported. They sampled 32 meals that adults ordered and found the sample mean to be 858 calories with a standard deviation of 49 calories. What are the null and alternative hypotheses?
The article "Well-Fed Crickets Bowl Maidens Over"† reported that female field crickets are attracted to males that have high chirp rates and hypothesized that chirp rate is related to nutritional status. The chirp rates for male field crickets were reported to vary around a mean of 60 chirps per second. To investigate whether chirp rate is related to nutritional status, investigators fed male crickets a high-protein diet for 8 days and then measured chirp rate. The mean chirp rate for the crickets on the high-protein diet was reported to be 101 chirps per second. Is this convincing evidence that the mean chirp rate for crickets on a high-protein diet is greater than 60 (which would then imply an advantage in attracting the ladies)? Suppose that the sample size and sample standard deviation are n = 32 and s = 40. You can test the relevant hypotheses to answer this question. A significance level of ? = 0.01 will be used. a) State the null and alternative hypotheses. H0: ? =…
Estimate the average number of feathers that a mature tom turkey has with 90% confidence interval by using a sample of 32 turkeys that had a mean of 3450 feathers and a standard deviation of 25 feathers.
A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below. Is there a statistically significant difference in the proportions of women delivering preterm among the three treatment groups? Run the test at a 5% level of significance. Give each of the following 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value. Preterm Delivery Total Yes No Experimental Drug Standard Drug Placebo Total 33 40 32 45 13 18 17 35 37 83 120
