A Marketing Study Was Conducted to Compare the Mean Age $t = 2.83$

A marketing study was conducted to compare the mean age of male and female purchasers of a certain product. Random and independent samples were selected for both male and female
Purchasers of the product. It was desired to test to determine if the mean age of all female
Purchasers exceeds the mean age of all male purchasers. The sample data is shown here:


Suppose the test statistic was calculated to be the value, $t = 2.83$ . Use the rejection region to state the correct conclusion when testing at alpha $= 0.05$ .

A) We reject $\mathrm { H } _ { 0 }$ .
B) We accept $\mathrm { H } _ { 0 }$ .
C) We fail to reject $\mathrm { H } _ { 0 }$ .
