Answer:
a1) 
a2)
b1) 
b2)
c) X is more likely to be within 1 GPa of 70 GPa in the random sample of part b because of the largeness in sample size and less scattering of data
Step-by-step explanation:
Mean value, 
Standard deviation, 
a1) sample size, n = 16
Mean of the sampling distribution of the sample mean = mean value, i.e.

a2) The standard deviation of the sampling distribution of the sample mean

b1) For sample size, n = 64
Mean of the sampling distribution of the sample mean = mean value, i.e.

a2) The standard deviation of the sampling distribution of the sample mean

c) X is more likely to be within 1 GPa of 70 GPa in the random sample of part b because it has a larger sample size, hence a decrease in the variability. This makes us easily determine the position of the sample around the population mean
Answer:
a=4 and b=-1

Answer:
1. yes 2. no
Step-by-step explanation:
for #2 it would have to be 0.57 and 0.570
Answer:14 weeks
Step-by-step explanation:288 x 14 = 4032
We have
y=x²+16
x=(+/-)√(y-16)
<span>exchange x by y and I get the inverse function
</span>the inverse is --------------- > y=(+/-)√(x-16)
the answer is y=(+/-)√(x-16)
