Step 5: Reject H0 if the pvalue is less than α. Interpret the statistical results
The pvalue of 0.00114 is less than the α value of 0.05. Therefore, H0 would be rejected at the level of significance 0.05 and the magazine price could be raised.
Inputs    Hypothesized Population Mean:  119155  Population Standard Deviation (sigma):  30000  Sample size (n):  300  Sample Mean (Xbar)  124450    Intermediate Calculations    Standard Error of the Estimate:  1732.0508  Test Statistic (z):  3.0570697    Results      One tailed, H0: Mu =>119155, p=  0.9989    One tailed, H0: Mu <=119155, p=  0.0011    Twotailed, H0: Mu = 119155, p =  0.0022 
 For the Alpha level given, H0 should be   Alpha:  0.01  0.05  0.1   not rejected  not rejected  not rejected       Rejected  Rejected  Rejected       Rejected  Rejected  Rejected 
One can be statistically confident in the conclusion to reject the null hypothesis H0 by performing calculations to derive the confidence intervals. Using the Excel function NORMSINV and inputting the necessary variables (see highlighted figures below), one can determine both the upper and lower
