A researcher wanted to determine if the population of a certain town had a mean income of $30,000. The significance level is to be a30.05. The output below was obtained from a TI calculator. T-Test u#30000 t=-2.236349263 P=.0399228234 X=22298 Sx=14200 n=17 The decision is to: O Reject the null hypothesis; There is enough evidence to conclude the mean is not 30,000 O Reject the null hypothesis; There is enough evidence to conclude the mean is 22,298 O Fail to Reject the null hypothesis; There is insufficient evidence to conclude the mean is 22,298 O Fail to Reject the null hypothesis; There is insufficient evidence to conclude the mean is not 30,000

Transcribed Image Text:A researcher wanted to determine if the population of a certain town had a mean income of $30,000. The
significance level is to be a30.05. The output below was obtained from a TI calculator.
T-Test
H#30000
t=-2.236349263
F=.0399228234
X=22298
Sx-14200
n=17
The decision is to:
O Reject the null hypothesis; There is enough evidence to conclude the mean is not 30,000
O Reject the null hypothesis; There is enough evidence to conclude the mean is 22,298
O Fail to Reject the null hypothesis; There is insufficient evidence to conclude the mean is 22,298
O Fail to Reject the null hypothesis; There is insufficient evidence to conclude the mean is not 30,000
