Answer:
The value of the test statistic z for this hypothesis test is -2.79
Step-by-step explanation:
Consider the provided information.
To calculate the test statistic use the formula:

Where, z is Test statistics, n is Sample size, p₀ = Null hypothesized value and
= Observed proportion.
p₀ = 0.50
Thus 1-p₀= 0.50
42% responded that if they had a cell phone, thus 
The sample size is 305.
Substitute the respective values in the above formula.



Hence, the value of the test statistic z for this hypothesis test is -2.79
Both of there numbers will result in a answer that is negative

Answer:
This equation is false
Step-by-step explanation:
First off the underscore (_) but even if we get rid of that and we try to solve:
7+7
?
=
14−6+2(45+55−668)
and because of the equal sign
14≠−1128
False.
