Answer:
479 = expected runs
0.220 = assumed batting average
Step-by-step explanation:
ˆy=−790+5400x
For an x value of 0.235, we have to calculate ˆy, or the predicted value. Plugging 0.235 in for x, we get
-790 + 5400 * 0.235 = 479
If ˆy = 400, we have to calculate x. Plug 400 in for y in our equation to get
400 = -790 + 5400x
add 790 to both sides to isolate the x and its coefficient
1190 = 5400x
divide both sides by 5400 to solve for x
x= 0.220
Answer:
Margin of error = 0.09
Confidence interval = (0.29, 0.41)
Step-by-step explanation:
Sample size, n = 1023
p = 38%
= 0.38
Standard deviation, σ = 1.5
Consider the level of confidence to be 95%
So, corresponding z* value for 95% confidence level = 1.96
Hence, confidence interval = p ± margin of error
= 0.38 ± 0.09
= (0.29, 0.47)
