Answers and Step-by-step explanation:
Hypotheses are:
H o=19.8
H 1 ≠19.8
Here we have following information:
s=2.45, X bar=20.1, n=50
So test statistics will be
t=20.1-19.8/(2.45/ =0.87
Degree of freedom : d f = n - 1 = 50 - 1 =49
Test is two tailed so critical value of the test is -1.30 and 1.30.
Rejection region:
if t < -1.30 and t > 1.30, reject H o
Since test statistics lie in the rejection region so we fail to reject the null hypothesis.
(b)
The observed significance of the test is
P value =0.3885
(c)
Since p value is greater than 0.20 so we fail to reject the null hypothesis.
The statement (C) the number of juice boxes must be an even number is correct.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a rule is “Multiply by 8"
Number of Packages: 3 5 6 8
Number of Juice Boxes: 24 40 48
The statements are:
- A. The number of juice boxes will always be greater than 24.
- B. The number of packages will always be greater than the number of juice boxes.
- C. The number of juice boxes must be an even number.
- D. The number of juice boxes will always be 21 more than the number of packages.
Number of package starts from 3
Applying the rule: "Multiply by 8.
Number of Juice Boxes = 3×8 = 24
The statement should be the number of juice boxes will always be greater than and equal to 24.
When we multiply even with odd we get an even number.
8 is an even number.
Thus, the statement (C) the number of juice boxes must be an even number is correct.

Hey there!
To solve this problem, first divide the numbers 240 and 6 . . .
240 divided by 6 = 40
Since Selma had 6 times as many coins as she did 4 months ago, the number of coins 4 months ago times the number 6 should equal 240.
40 x 6 = 240
The number 40 is correct.
Selma had 40 coins 4 months ago.
Hope this helps you.
Have a great day!
