Answer: (29.35, 40.95)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-
, where 
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
As per given , we have
n= 37
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, the confidence interval for the population mean will be :
Hence, a 95% confidence interval for the population mean = (29.35, 40.95)
Answer:
x=6
Step-by-step explanation:
a²+b²=c²
x²+8²=10²
x²+64=100
x²=36
x=6
if u have any questions abt how to solve lmk
You would just replace x with 2 in the part equation and solve for it. So 3(2) - 7. This is equal to -1
Convert all to decimals
percent means parts out of 100
13%=13/100=0.13
'of' means mutiply
Tom=13% of 4
tom=0.13 times 4
tom=0.52 lb
Lisa=0.6 lb
Jane=0.12 of 4
jane=0.12 times 2
jane=0.48
Tom=0.52
Lisa=0.60
Jane=0.48
Lisa used the most
Answer:
ouuuuu that is a really good question
