1. We are interested in testing whether the variance of a population is significantly less than 1.44. The null hypothesis for this test is
a. Ho: s2 < 1.44
b. Ho: s2 >= 1.44

2. How do I do this by the calculator?

A random sample n=30 is obtained from a population with unknown variance. The sample variance s2 = 100 and the sample mean is computed to be 85. Test the hypothesis at α = 0.05 that the population mean equals 80 against the alternative that it is more than 80. The null hypothesis Ho: µ = 80 versus the alternative H1: Ho: µ > 80. Calculate the test statistic from your sample mean. Then calculate the p-value for this test using...

Let x represent the number of mountain climbers killed each year. The long-term variance of x is approximately σ2 = 136.2. Suppose that for the past 11 years, the variance has been s2 = 107.1. Use a 1% level of significance to test the claim that the recent variance for number of mountain-climber deaths is less than 136.2. Find a 90% confidence interval for the population variance. (a) What is the level of significance? State the null and alternate hypotheses....

A manufacturer is interested in the output voltage of a power supply used is a PC. Output voltage is assumed to be normally distributed with standard deviation 0.25 Volts, and the manufacturer wishes to test H0: μ = 5 Volts against Ha: μ≠ 5 Volts, using n = 8 units at 5% significance level. If the sample mean is 5.10, then the corresponding p-value is 0.295 0.258 0.05 1.13 ) In testing the hypotheses H0: μ = 200 vs. Ha:...

We are interested in estimating the mean amount of rain last month in our county. It is known that the population standard deviation is 1.5 inches generally for the month of interest. 49 instruments that measure rainfall were placed throughout the county randomly. The sample mean from the instruments was 5.2 inches. Calculate a 95% confidence interval for the population mean of rainfall last month in the county.
