Answer:
0.052 > 0.05, which means that there is not significant evidence that the population mean is less than a.
Step-by-step explanation:
At the null hypothesis, we test if:

At the alternative hypothesis, we test if:

Standard significance level of 0.05:
If the p-value > 0.05: no significant evidence that the population mean is less than a.
p-value < 0.05: significant evidence that the population mean is less than a.
You obtain a P-value of 0.052. Which of the following statements is true?
0.052 > 0.05, which means that there is not significant evidence that the population mean is less than a.
38.384 inches represent 2300 miles
THE WORK IS: 2300 divided by 65 equals 38.384
I believe your answer is (-2,4)
Let x - hours Carlos drove ; Let y - hours Maria drove
Equation 1: x + y = 4.4
x = 4.4 - y
Equation 2: 55x + 50y = 233
55(4.4 - y) + 50y = 233
242 - 55y + 50y = 233
-5y = 233-242
-5y = -9
y=9/5 or 1.8 hours Maria drove
To find time Carlos drove:
x=4.4 - 1.8
x = 2.6 hours
