An oceanographer wants to test, on the basis of the mean of a random sample of size n = 35 and at the 0.05 level of significance, whether the average depth of the ocean in a certain area is 72.4 fathoms, as has been recorded. What will she decide if she gets x = 73. 2 fathoms, and she can assume from information gathered in similar studies that o = 2. 1 fathoms? Instructions: Assume a two-tailed test, in addressing the problem obtain the value of the test statistic and its corresponding p – value up to four decimal places. 23D 1.2511; р — value 0. 0512 Оz- 2.5543; р— value — 0.0523 Ох 3D 2.2537;B р— value = 0.0121 Ох3 2. 2537%; р — - value 0.0242
