Answer:
95% confidence interval for the mean ARSMA score for first-generation Mexican Americans
(2.13264 , 2.58736)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Mean of the Population = 3.0
Standard deviation of the Population = 0.8
Given Mean of the sample(x⁻ ) = 2.36
Standard deviation of the sample (S) = 0.8
size of the sample = 50
Level of significance =0.05
Degrees of freedom = n-1 = 50-1 = 49
<u><em>Step(ii)</em></u>:-
95% confidence interval for the mean ARSMA score for first-generation Mexican Americans
( 2.36 - 0.22736 , 2.36 + 0.22736)
(2.13264 , 2.58736)
<u><em>Final answer</em></u>:-
95% confidence interval for the mean ARSMA score for first-generation Mexican Americans
(2.13264 , 2.58736)
Answer:
--- (a)
---- (b)
Step-by-step explanation:
Given
Per ride (r) = $8
Per baseballs (s) = $6
Total = $100
Required
Represent using an equation
If 1 ride is $8.
r rides would be 8r
If 1 baseball is $6
s baseballs would be 6r.
So, total is:
Solving (b):
Value of s when r = 14
Substitute 14 for r
Solve for 6s
Solve for s
