Answer:
0.02566
0.972559
Step-by-step explanation:
Given that :
Sample size (n) = 36
σ² = 6
sample variance S^2
a) greater than 9.1;
b) between 3.5 and 10.5.
The degree do freedom (df) = n - 1
S² > 9.1
P(S² > 9.1) = X² > ((n - 1) * S²) / 6
P(S² > 9.1) = ((36 - 1) * 9.1) / 6
P(S² > 9.1) = (35 * 9.1) / 6
P(S² > 9.1) = 53.083
P(X² > 53.08) = 0.02566 ( chi square distribution calculator)
b) between 3.5 and 10.5.
((36 - 1) * 3.5) / 6 ≤ S² ≤ ((36 - 1) * 10.5) / 6
20.416666 ≤ S² ≤ 61.25
Using the Chisquare distribution calculator :
P(X² > 20.42) = 0.9765
P(X² > 61.25) = 0.003941
Hence,
0.9765 - 0.003941 = 0.972559

Step-by-step explanation:
Q7
- g(s) = 2s + 3,
- g(-2) = 2(-2) + 3 = -4 + 3 = -1
Q8
- h(x) = x² - x + 7
- h(4) = 4² - 4 + 7 = 16 + 3 = 19
Q9
Basic channels = $32.50, each premium channel = $4.95
a) <u>Equation:</u>
b) <u>Table:</u>
- p = 0 ⇒ c = 32.50
- p = 1 ⇒ c = 4.95 + 32.50 = 37.45
- p = 2 ⇒ c = 2*4.95 + 32.50 = 42.40
- p = 3 ⇒ c = 3*4.95 + 32.50 = 47.35
- p = 4 ⇒ c = 4*4.95 + 32.50 = 52.30
