Zadanie

Katie grows two varieties of pears—Bosc and Anjou. She took a sample of each variety to test if their mean weights were significantly different. Here is a summary of her results (weights are shown in grams):
Pear weights
VarietynMeanStDevSE mean
Bosc301798.51.55
Anjou301637.01.28
95% CI for μBμA:(11.97,20.03)
Katie wants to use these results to test H0μB=μA versus HaμBμA. Assume that all conditions for inference have been met.
Based on the interval, what do we know about the corresponding P-value and conclusion at the α=0.05 level of significance?
