Hello, I would like to know the process and the result of these exercises from Statistics. Thank you!
You have just received a report that specifies that the test statistic (Z) is 1.5.In the report, it, also, mentions that the significant level (alpha) is .05 for a two-tail test.
Calculate the p-Value to determine if the test statistic is significant or not.
Susan Williams has been the production manager of Medical Suppliers, Inc., for the past 17 years. During the past 5 years, the demand for No-Stick has been fairly constant.On average, sales have been 87,000 packages of No-Stick. Susan has reason to believe that the distribution of No-Stick follows a normal curve, with a standard deviation of 4,000 packages.
What is the probability that sales will be less than 81,000 packages?
