The average fruit fly will lay 421 eggs into rotting fruit. A biologist wants to see if the average wil be lower for flies that have a certain gene modified. The data below shows the number of eggs that were laid into rotting fruit by several fruit flies that had this gene modified. Assume that the distribution of the population is normal. 429, 426, 402, 401, 393, 424, 426, 415, 416, 422, 414, 428 What can be concluded at the the a = 0.05 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: H: 421 c. The test statistic - -1.358 (please show your answer to 3 decimal places.) d. Based on this, we should fail to reject e. Thus, the final conclusion is that...
