You wish to test the following claim (Ha) at a significance level of α=0.02 Ho:μ=54.6 Ha:μ>54.6 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=87 with mean M=55.8and a standard deviation of SD=7.7 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... A-less than (or equal to) αα B-greater than αα This test statistic leads to a decision to... A-reject the null B-accept the null C-fail to reject the null As such, the final conclusion is that... A-There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 54.6. B-There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 54.6. C-The sample data support the claim that the population mean is greater than 54.6. D-There is not sufficient sample evidence to support the claim that the population mean is greater than 54.6.
You wish to test the following claim (Ha) at a significance level of α=0.02
Ho:μ=54.6
Ha:μ>54.6
You believe the population is
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...
A-less than (or equal to) αα
B-greater than αα
This test statistic leads to a decision to...
A-reject the null
B-accept the null
C-fail to reject the null
As such, the final conclusion is that...
A-There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 54.6.
B-There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 54.6.
C-The sample data support the claim that the population mean is greater than 54.6.
D-There is not sufficient sample evidence to support the claim that the population mean is greater than 54.6.
