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.

In order to solve these you first need a ratio.
From what we can tell, the ration from LEFT to RIGHT is:
2:3
Therefore, in order to have a 2:3 ratio, we need 5 parts total (2 parts on left + 3 parts on right = 5 total parts!)
A) 60
B) 90
Answer:
0.25
Step-by-step explanation:
<em>there are four people being considered for the position</em>
total=4
<em>Three of the applicants are over 60 years of age</em>
4(total) - 3 (over 60 years)= 1 below 60 years
<em>Two are female</em>
4(total) - 2 (female)= 2 male
<em>only one female is over 60</em>
2(female)-1 (female over 60)= 1 female below 60
<u>then the four candidates are</u>
<u>1. female over 60</u>
<u>2. female below 60</u>
<u>3. male over 60</u>
<u>4. male over 60</u>
probability that the candidate is over 60 and female =1/4=0.25
She walked 1/10 of a mile in one minute
work: 1/2 a mile is 0.5 and 0.5 divided by 5 is 0.1 so you get 0.1 mile for each minute
