Answer:
Step-by-step explanation:
X=6 y=10
x=57 y=10
57/6=9.5
10*9.5 =95
y=95
Answer: 45/60 in simplest form would be B. 3/4
Answer:
65.04<x<68.96
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = x ± z*s/√n
x is the mean = 67
z is the 95% z score = 1.96
s is the standard deviation = 8
n is the sample size = 64
Substitute;
CI = 67 ± 1.96*8/√64
CI = 67 ± 1.96*8/8
CI = 67 ± 1.96
CI = (67-1.96, 67+1.96)
CI = (65.04, 68.96)
Hence the confidence interval for the mean of the population is between 65.04<x<68.96
