Step 1
Since we do not know the population standard deviation, we use the t-distribution. The formula for the t-test statistic is: t = (M - μ) / (SD / sqrt(n)) Plugging in the values we have: t = (58.1 - 62.1) / (8.3 / sqrt(17)) = -2.236 So the test statistic is Show more…

You wish to test the following claim (Ha) at a significance level of α=0.05. Ho: μ=52.8 Ha: μ≠52.8 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=55 with mean M=54 and a standard deviation of SD=6.7. 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... less than (or equal to) α greater than α 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 52.8. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 52.8. The sample data support the claim that the population mean is not equal to 52.8. There is not sufficient sample evidence to support the claim that the population mean is not equal to 52.8.

You wish to test the following claim ( H a ) at a significance level of α = 0.02 . H o : μ = 54.7 H a : μ < 54.7 You believe the population is normally distributed and you know the standard deviation is σ = 7.6 . You obtain a sample mean of M = 53.7 for a sample of size n = 35 . 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) α greater than α 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 less than 54.7. There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 54.7. The sample data support the claim that the population mean is less than 54.7. There is not sufficient sample evidence to support the claim that the population mean is less than 54.7.

You wish to test the following claim (Ha) at a significance level of α = 0.10. Ho: μ = 73.5 Ha: μ > 73.5 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 114 with mean M = 81.2 and a standard deviation of SD = 19.2. 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) α or greater than α 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 greater than 73.5, there is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 73.5, the sample data support the claim that the population mean is greater than 73.5, there is not sufficient sample evidence to support the claim that the population mean is greater than 73.5.
