Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
It’s the first one since parallel means same slope
Answer: See attached
Step-by-step explanation:
[] Since the inequality uses greater than (>) and <em>not</em> greater than or equal to (≥), the line will be dashed.
[] The inequality is greater than (>) so we will shade above the line as values "above" are greater.
The vertex would be (-2,4)
Answer:
A 25% tip on a bill of $68.28 rounded to $70 would be <u>$17.50</u>
STEPS
<em>Step 1: </em>Round $68.28 to $70.00
<em>Step 2:</em> convert 25% to a decimal-------- .25
<em>Step 3:</em> multipy .25 x 70= 17.5
