Answer:
80+50f
Step-by-step explanation:
f= hours of labor. Your equation should be 80+50f
Slope = (y2 - y1)/(x2 - x1) = (1 - 7)/(10 - 1) = -6/9 = -2/3
Answer: a) 84 and b ) 2084
Step-by-step explanation:
Given : Sample standard deviation : s= $22.82
(Population standard deviation is unknown ) , so we use t-test.
Critical value or the 95% confidence intervals :
Formula to find the sample size :

a) E = 5


i.e. Required sample size : n= 84
b) E = 1


i.e. Required sample size : n= 2084
