No, because the test is two-tailed. B. Yes, because ngreater than or equals30. C. Yes, because the sample is random. D. No, because ngreater than or equals30. Part 2 (b) If x overbarequals99.9 and sequals5.8, compute the test statistic. The test statistic is t 0equals enter your response here. (Round to two decimal places as needed.) Part 3 (c) Draw a t-distribution with the area that represents the P-value shaded. Choose the correct graph below. A. A symmetric bell-shaped curve is plotted over a horizontal axis. Two vertical lines, equidistant from the curve's peak at the center, extend from the axis to the curve on the left and right sides of the graph. The area under the curve between the vertical lines is shaded. B. A symmetric bell-shaped curve is plotted over a horizontal axis.
