Consider the following hypothesis statement using=0.05 and data from two independent samples:

H0120.5vsHa12<0.5

x1=96.5,s1=6.5andn1=14

x2=82.9,s2=11.2andn2=18

Assume the samples are independent and normally distributed with unequal variance. Use 3 decimal places and DF = 28.

Calculate the test statistic, p-value and state the conclusions

Group of answer choices

test statistic = 4.311, p-value > 0.05, fail to reject H0

test statistic = 4.145, p-value < 0.05, reject H0

test statistic = -1.701, p-value = 0.05. Because the p-value is equal to , we cannot reach any conclusions about the hypothesis test.

test statistic = -3.86, p-value < 0.05, reject H0
