Answer:
B. i and iii
Step-by-step explanation:
There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution
Hypothesis
H0: u <= 15
H1: u > 15
Mean of x = 16.6
S = 2.22
Test statistic used is t test
16.6 - 15 / 2.22/√24
= 3.531
We find the critical value
Degree of freedom = 24-1 = 23
This is a one tailed test
Critical value = 1.714
We find p value using Ms excel T distribution function
= 0.000894
To make the decision
3.531 > 1.714 so we conclude that
I.) Reject null hypothesis
Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.
The answer option Is B
Answer:
3/26
Step-by-step explanation:
Probability of the first box to have the secret decoder ring is 18 out of 52:
Probability of the second box to have the ring is 17 out of 51, because one box with the ring already selected and not counted:
Probability that both of them have the secret decoder ring:
<u>So the answer is</u> 3/26
None of them have a solution of x, but 5x=15, 7x-2=19, and 5x+6=21 all have the same answer of x=3
Step-by-step explanation:
Is that the whole question or can you give me more information?
There are 12 different ways she could take a penny, a nickle, and a dime out of here pocket and only pick 2. What i did was i took 2 and 3 and multiplied them. because i can pick 2 coins, and there are 3 coins in total. After i multiplied them i got 6, then i got 2 and multiplied it by 6 and came out with 12. The reason why i did that is because there are 6 outcomes so far then you have to multiply them by 2 to get all of your complete outcomes. I hope i could help!!! Please give me brainliest!!! Have a great day =D!!!
