You wish to test the following claim (HaHa) at a significance level of =0.

Description


You wish to test the following claim (HaHa) at a significance level of α=0.05.Ho:μ=74.1Ho:μ=74.1        Ha:μ≠74.1Ha:μ≠74.1 You believe the population is normally distributed and you know the population standard deviation is σ=7.4. You obtain a sample mean of M=71.4 for a sample of size n=57. What is the test statistic for this sample? (Report answer accurate to three decimal places.)  test statistic =  _____________ What is the p-value for this sample? (Report answer accurate to four decimal places.)  p-value =  _____________ The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null fail to reject the null As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 74.1. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 74.1. The sample data support the claim that the population mean is not equal to 74.1. There is not sufficient sample evidence to support the claim that the population mean is not equal to 74.1.
