Tell if the statement is true ir false.Please do full calculation by writing every formulae on how to calculate sample size,standard deviation etc.


Suppose that I take a simple random sample of University of Regina students and construct a 95% confidence interval for the mean IQ of all U of R students. My confidence interval is 110 ± 3. Now I want to use the same data to conduct a level α = 0.01 significance test of H0: the mean IQ of all U of R students is 112, against the alternative Ha: the mean IQ of all U of R students is not 112. Based on the confidence interval, I would reject H0.

If you were conducting the two-sided hypothesis test, Ho: μ = 65 Ha: μ ≠ 65 at the 5% significance level, would you reject or fail to reject Ho. I don't want you to conduct a full hypothesis test here. Instead, note that one of the above CIs is equivalent to conducting this test. Tell me which interval and explain why you decided to reject or fail to reject based on this interval. 1. Suppose you are going to construct...

A random sample of 22 STAT 250 students was collected and the file size of Data Analysis 2 was recorded. The data was measured in megabytes. The instructors of the course claim that the file size will be different from 5 megabytes. Consider the population of all file sizes to be right skewed. Using a= 0.01, is there sufficient evidence to conclude that the mean file size of Data Analysis 2 is different from 5 megabytes? Conduct a full hypothesis...
