Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 36 months from January 2006 through December 2020, the mean number of tornadoes per month in the United States was about 104. Assume the population standard deviation is 118.

The result of testing He:H= 13 against H:u#13. at 0.05 level of significance, will be O Do not reject the nulhhypothesis because 13 is between 11 and 17 OThere is insufficient information to make any conclusion about the hypothesis test O Reject the null hypothesis because 13 is more than 11 O Do not reject the the null hypothesis because 13 is less than 17 QUESTION
