A manufacturer of trucks wishes to test if the hoods being received from a supplier have an average weight greater than 17 pounds with a level of significance of 0.05. A random sample size of size 12 produced a sample mean of 17.2 pounds and a test statistic value of 1.54 calculated using the sample standard deviation. Which one of the following is the correct decision to make for this hypothesis test?

Question
A manufacturer of trucks wishes to test if the hoods being received from a supplier have an
average weight greater than 17 pounds with a level of significance of 0.05. A random sample size
of size 12 produced a sample mean of 17.2 pounds and a test statistic value of 1.54 calculated
using the sample standard deviation. Which one of the following is the correct decision to make
for this hypothesis test?
H:µ=17
H :µ>17
Reject the null hypothesis at the .05 level
significance because 17.2 > 17
O Do not reject the null hypothesis at the .05 level of significance because 1.54 < 2.201
O Do not reject the null hypothesis at the .05 level of significance because 1.54 < 1.796
O Reject the null hypothesis at the .05 level of significance because 1.54 > 1.363
