Answer:
187.5 ft²
Step-by-step explanation:
15 x 15 = 225
1/2(5 x 15) = 37.5
225 - 37.5 = 187.5
Answer:
B.) 6
Step-by-step explanation:
Given the data:
64 53 60 60 56 58 51 55 60
Reordered data : 51, 53, 55, 56, 58, 60, 60, 60, 64
Interquartile range = upper quartile (Q3) - Lower quartile (Q1)
Q3 = 3/4(n+1)th term
n = sample size = 9
Q3 = 3/4(9+1) = 3/4 (10) = 30/4 = 7.5 th term
Q3 = 60
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(9+1) = 1/4 (10) = 10/4 = 2.5 th term
Q1 = (53 + 55) / 2
Q1 = 54
Q3 - Q1
60 - 54 = 6
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.
