Please help. I'm getting some of these wrong. Answers are below.

You wish to test the following claim (Ha) at a significance level of =0.001. Ho:=59.5 Ha:>59.5 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data:

Column A Column B Column C Column D Column E
78.9 50.3 71.2 52.5 93.6
54.1 62.2 55.9 80.1 64.5
59 62.9 59 61.4 56.8
69.5 53 62.9 72.9 76.7
75.7 51.4 36.1 90 72
77.2 63.7 73.3 76.2 53
47.6 73.8 68.7 58.6 45.3
54.5 91.6 74.2 60.6 64.5
46.9 49 42.3 79.5 38.1
57.3 50.9 57.7 86.4 72
77.2 91.6 93.6 43.4 33.4

A)What is the test statistic for this sample?Round to 4 decimal places. test statistic = 2.2672. This is wrong. B)What is the p-value for this sample?Round to 4 decimal places. p-value = 0.0137 This is wrong.

C)Does this test statistic: I said accepted. This is wrong.

  • reject the null
  • accept the null
  • fail to reject the null
  • D)Is the conclusion that: I said option 2. Which is wrong.
  • There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 59.5.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 59.5.
  • The sample data support the claim that the population mean is greater than 59.5.
  • There is not sufficient sample evidence to support the claim that the population mean is greater than 59.5.
