During a wisdom teeth removal procedure, 1, 2, 3, or 4 wisdom teeth are removed, depending on the patient's needs. Records indicate that nationwide, the mean number of wisdom teeth removed in a procedure is u = 3.67, with a standard deviation of o=0.86. Suppose that we will take a random sample of G %3D wisdom teeth removal procedures and record the number of wisdom teeth removed in each procedure. Let x represent the sample mean of the 6 procedur Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find (the mean of the sampling distribution of the sample mean). %3D (b) Find o- (the standard deviation of the sampling distribution of the sample mean). Continue

On average, a banana will last 6.6 days from the time it is purchased in the store to the time it is too rotten to eat. Is the mean time to spoil different if the banana is hung from the ceiling? The data show results of an experiment with 14 bananas that are hung from the ceiling. Assume that that distribution of the population is normal. 7.9, 6, 5.5, 8.1, 7.9, 8.8, 6.6, 8.7, 6.2, 6.3, 8.6, 6.7, 8.5, 9.3 What can be concluded at the the α = 0.01 level of significance level of significance? a. For this study, we should use [t-test for a population mean b. The alternative hypothesis would be: H₁: Hv c. The test statistic d. Based on this, we should Select an answer e. Thus, the final conclusion is that ... Select an answer (please show your answer to 3 decimal places.) the null hypothesis.
