= 900-120-158-126-125-121-139
Step-by-step explanation:
If events E1 and E2 are mutually exclusive, it means that it is impossible for them to happen together. The probability of the occurrence of one or more of these events is the sum of their individual probabilities. The answer for this item would be,
P(E) = P(E1) + P(E2) + ...
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.
Answer:
-15.41
Step-by-step explanation:
6.7 * (-2.3) =
Lets break it into parts
6.7 * .3 = 2.01
6.7 * 2 = 13.4
Add them together
13.4+ 2.01
15.41
A positive times a negative is a negative
-15.41
The answer only has digits to the hundredths place, so no rounding is required.
