You wish to test the Ho: µ = 52.4 H1:µ < 52.4 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size 82 with a mean of 49.4 and a standard deviation of 15.2. What is the critical value for this test? (Report answer accurate to 3 decimal places.) What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) This test statistic leads to a decision to O reject the null O accept the null O fail to reject the null As such, the final conclusion is that O there is sufficient evidence to conclude that the population mean is equal to 52.4. there is not sufficient evidence to conclude that the population mean is equal to 52.4. O there is sufficient evidence to conclude that the population mean is less than 52.4. O there is not sufficient evidence to conclude that the population mean is less than 52.4.

Question
You wish to test the following claim at a significance level of 0.02. Ho: µ = 52.4 H1: µ < 52.4 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size 82 with a mean of 49.4 and a standard deviation of 15.2. What is the critical value for this test? (Report answer accurate to 3 decimal places.) What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) This test statistic leads to a decision to O reject the null accept the null O fail to reject the null As such, the final conclusion is that O there is sufficient evidence to conclude that the population mean is equal to 52.4. O there is not sufficient evidence to conclude that the population mean is equal to 52.4. there is sufficient evidence to conclude that the population mean is less than 52.4. O there is not sufficient evidence to conclude that the population mean is less than 52.4.
