Answer:
Variance =9.2983, 27.6927
Standard deviation = 3.0493, 5.2624
Step-by-step explanation:
n = 20
S = 14.75
X² = chisquare
N-1 = degree of freedom
Alpha = 0.1
Alpha/2 = 0.1/2 = 0.05
1-0.1/2 = 0.95
Using statistics table
X² 19,0.05 = 30.14
X² 19, 0.95 = 10.12
A. 19(14.75)/30.14 , 19(14 75)/10.12
= 9.2983, 27.6927 for the variance of the population
B. Standard deviation = square root of variance
= √9.2983, √27.6927
= 3.0493, 5.2624

Answer:
10
Step-by-step explanation:
Given that Sasha has won 0 games in the 40 games she has played.
Let she needs to win x game in a row, so
Total game she played = 40 + x
The number of the game she won is x, which is 20% of the total game she played, so
x = 20% of (40+x)
Hence, she needs to win 10 games in a row.
