We can notice that there is a change:
The votes for Perez and Chung decreased but the votes for Stevens increased
Well, first off 1 hr =60 minutes. 60 min - 45 min = 15 minutes extra. what is one hour before 4:15? 3:15! Add the subtracted 15 minutes to get 3:30... Hope this helps
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:
Step-by-step explanation:
Given that the weights of bags filled by a machine are normally distributed with a standard deviation of 0.055 kilograms and a mean that can be set by the operator.
Let the mean be M.
Only 1% of the bags weigh less than 10.5 kilograms
i.e. P(X<10.5) = 0.01
corresponding Z value for P(Z<z) = 0.01 is -0.025
i.e. 10.5 = M-0.025(0.055)
Solve for M from the above equation
M = 
Rounding off we get
10.50 kgs
Mean weight should be fixed as 10.50 kg.
