Test the given claim. Assume that a simple random sample is selected from a normally distributed population. Use the critical va
alukav5142 [94]

Answer:

The standard deviation has changed for the worse

Step-by-step explanation:

We need to compare the sample standard deviation of 52.3 to the known population standard deviation of 43.7.  The test we will use will use Chi-Square distribution...

The hypothesis for this test are...

H0: σ = 43.7

Ha:  σ ≠ 43.7  

This is a 2 tailed test.  

We have n = 81

s = 52.3

s² = 52.3² = 2735.29

σ = 43.7

σ² = 1909.69

The degrees of freedom are:  n - 1, in this case, 80  

Our significance level is 95%, so our critical values are

Χ² < 57.153 and Χ² > 106.629

The test static is found with the formula:

Χ² = [(n - 1)s²]/σ²

Plug in what we have and find the test stastic....

Χ² = [80(2735.29)]/1909.69

Χ² = 114.586

114.586 > 106.629, we reject the null hypothesis.  There is evidence that shows that the standard deviation has changed.  The evidence suggests that it has increased, which would make the new method worse than the old method.

A die is rolled 20 times. given that three of the rolls came up 1, five came up 2, four came up 3, two came up 4, three came up
Serjik [45]

Solution:

Number of times a die is rolled = 20

1 - 3=A

2 - 5=B

3 - 4=C

4 - 2=D

5 - 3=E

6 -  3=F

Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times

            = Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes

= 6! × [ 3! × 5! × 4!×2!×3!×3!]

= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]

= 895795200  Ways
