Is the average smaller for college students? The data below shows the results of a survey of 13 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 39, 37, 36, 37, 36, 37, 38, 40, 33, 40, 27, 25, 41 What can be concluded at the the αα = 0.01 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 3 decimal places.) The p-value is αα Based on this, we should the null hypothesis.
- Determine the critical value for a left tailed test of a population mean at the a= 0.01 level of significance based on a sample size of n= 9.Where are the critical region(s) located in a z-distribution if a two-tailed hypothesis test was conducted using an alpha = 0.0892? Report the complete z-score (no rounding)The life span of a component is known to be distributed as normal with standard deviation 40 hours. It is claimed that the mean life span such components is 800 hours.
