10:55You want to estimate u, the mean number of daysbetween when a female squabbit is born,and when she first gives birth to offspring if she lives incaptivity. For our 25 randomlyselected female squabbits, the mean number of daysbetween being born and giving birth was407 days with a standard deviation of 52 days. Assumethat the number of days between birthand giving birth is Normally distributed.Show all of your work including what you are calculatingat each step (with the appropriatesymbols) as you find a 95% confidence interval for u.Tell me whatu and what the 95% confidence intervalrepresent].....................................

Here, sample size is 25. Sample mean = 407. Standard deviation is 52. The sample size, n is 25. Using the Excel formula “=NORM.S.INV (0.975)”The z-critical value for 90% confidence interval is 1.96.

The blue catfish (Ictalurus Furcatus) is the largest species of North Amercian catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to Amercian Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. If you are going to test this claim, what would be your null and alternative hypotheses? Ho: HA: p> v Submit Question
