A botanist would like to test the hypothesis of zero which says that min diameter flowers for Woad was 9.6 cm. He took in random one sample with n = 80 and will receive zero hypothesis if min diameter of sample flower is between 9.3 cm and 9.9 cm, and will reject hypothesis null otherwise. The decision stated what would he take and whether his decision was a wrong decision if:
a) min sample is 10.2 cm long and µ = 9.6 cm;
b) min sample is 10.2 cm long and µ = 9.8 cm;
c) min samples are 9.2 cm and µ = 9.6 cm;
d) min samples were 9.2 cm and µ = 9.8 cm

The Canadian government would like to test the hypothesis that
the standard deviation for the hourly wage for men is equal to the
standard deviation for the hourly wage for women. The sample size
for men is 11 with sample standard deviation 2.25 and the sample
size for women is 9 with standard deviation 3.75. Assume that

that the average debt load of graduating students with a bachelor's
degree is equal to $17,000. A random sample of 34 students had an
average debt load of $18,200. It is believed that the population
standard deviation for student debt load is $4,200. The α is set to
