Since is a two-sided check the p worth would be:

*
1.45)=0.147" alt="p_v =2*P(z>1.45)=0.147" align="absmiddle" class="latex-formula">

B. 0.1470

B.There is not adequate evidence come conclude that the median weekly household expenditure top top groceries in Pearland is significantly different native $125.

Step-by-step explanation:

Notation

*
represent the sample mean

*
represent the population standard deviation because that the sample

*
sample dimension

*
represent the worth that we desire to test

*
represent the significance level because that the hypothesis test.

z would stand for the statistic (variable of interest)

*
stand for the p value for the test (variable of interest)

State the null and alternate hypotheses.

We should conduct a hypothesis in bespeak to check if the mean is equal to 125 or not, the mechanism of hypothesis would be:

Null hypothesis:

*

Alternative hypothesis:

*

z-test: "Is provided to compare team means. Is just one of the most usual tests and also is used to recognize if the mean is (higher, less or no equal) come an specified value".

Calculate the statistic

The statistic because that this instance is

*

P-value

Since is a two-sided test the p worth would be:

*
1.45)=0.147" alt="p_v =2*P(z>1.45)=0.147" align="absmiddle" class="latex-formula">

B. 0.1470

Conclusion

If us compare the ns value and also the meaning level given

*
we check out that
*
\alpha" alt="p_v>\alpha" align="absmiddle" class="latex-formula"> for this reason we have the right to conclude that we have enough evidence come FAIL disapprove the null hypothesis. And the ideal conclusion would be:

B.There is not adequate evidence come conclude the the typical weekly family members expenditure ~ above groceries in Pearland is significantly different from $125.
