Q14. It is of interest to determine whether the average recovery time (in days) of patients who underwent a newly approved bone reconstruction procedure is faster than 80 days. Suppose that based on the Shapiro-Wilk test, there is sufficient evidence that the recovery time is not normally distributed. The appropriate procedure to answer the research objective is O Chi-square goodness-of-fit test O Mann-Whitney test O-test on one population meani O Wilcoxon-signed rank test Q15. The company that produces Gayant bikes decided to replace the gears used for its ten-speed racing bikes. The winning supplier promises that their gear diameter has a variance of at most 0.0001 mm². From a sample of 100 measurements, the estimated standard deviation is 0.06 mm. The alternative hypotheses for testing the supplier's promise is. O the mean of the gear diameters is less than 0.06 mm O the variance of the gear diameters is less than 0.0036 mm² O the mean of the gear diameters is greater than 0.01 mm O the variance of the gear diameters is greater than 0.0001 mm²
