An Economist Conducted a Hypothesis Test to Test the Claim $\begin{array}{l}\mathrm{H}_{0}: \mu=\$ 7.15 \\\mathrm{H}_{\mathrm{a}}: \mu<\$ 7.15\end{array}$

An economist conducted a hypothesis test to test the claim that the average cost of eating a meal away from home decreased from 2009 to 2010. The
Average cost of eating a meal away from home in 2009 was $7.15 per person per meal. Assume that
All
Conditions for testing have been met. He used technology to complete the hypothesis test.
Following is his
Null and alternative hypothesis and the output from his graphing calculator. $\begin{array}{l}\mathrm{H}_{0}: \mu=\$ 7.15 \\\mathrm{H}_{\mathrm{a}}: \mu<\$ 7.15\end{array}$
$\begin{array} { | l | } \hline \text { T-Test } \\\mu < 7.15 \\t = - 1.043281062 \\p = .1527187422 \\\bar { x } = 6.95 \\S x = 1.05 \\n = 30 \\\hline\end{array}$
Choose the statement that contains the correct conclusion regarding the hypothesis and the original
Claim.

A) Reject the null hypothesis; there is not sufficient evidence to support the claim that the average cost of eating away from home has decreased since 2009.
B) Fail to reject the null hypothesis; there is sufficient evidence to support the claim that the average cost of eating away from home has decreased since 2009.
C) Fail to reject the null hypothesis; there is not sufficient evidence to support the claim that the average cost of eating away from home has decreased since 2009.
D) Reject the null hypothesis; there is sufficient evidence to support the claim that the average cost of eating away from home has decreased since 2009.
