A sample of 20 is taken, resulting in a mean of 16.45 and standard deviation of 3.59. Assume that x is normally distributed and used alpha of 0.5 to test hypotheses.
i know for this problem you would use the p^+or-z(sqaureroot of p times q over n) But i am unsure after you plug those numbers which table to use
A hypothesis states the mean is 50. If a sample of 35 test this what is the value of b if population standard deviation is 7 and the alternative mean is 52. use alpha of 0.1
For this problem i am totally unsure of what formula to use
A complete, neat and step-by-step solution is provided in the attached files with regards to finding a hypothesis for a given scenario.
