The significance level shows that z approximately equals 1.41 for a p-value of 0.078642.
<h3>How to calculate the p-value?</h3>
Based on the complete question, the sample proportion for city A will be:
= 54/90 = 0.60
The sample proportion for city B will be:
= 63/90 = 0.70
Using the table given, it can be deduced that the test statistic value will be 1.41. Therefore, the p-value will be 0.078652 in the Excel function.
Since the p-value is greater than 0.05, then we fail to reject the null hypothesis that there is no difference in the commute time.

I'm not sure if this is correct but here is the answer:
Exact form:
x=-3/2
decimal form:
x=-1.5
mixed number form:
x=-1 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
y = (1/4)x - 1
Step-by-step explanation:
Start with the general slope-intercept form: y = mx + b. Subst. -1 for b and (1/4) for m. Then,
y = (1/4)x - 1
To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.
Then, divide by 3 on each side.
So, c = 7.
