Question 4) Given that, sample size (n) = 25
sample mean = 4.79
population standard deviation = 1.2
The null and alternative hypotheses are,
H0 : mean = 5
H1 : mean < 5
Using TI-83 plus calculator we get,
p-value = 0.1908
Question 7) Given that, sample size (n) = 100
sample mean = 6.35
population standard deviation = 60
The null and alternative hypotheses are,
H0 : mean = 16
H1 : mean < 16
Using TI-83 plus calculator we get,
p-value = 0.0539
Question 8) Given that, sample size (n) = 144
sample mean = 49.0
population standard deviation = 84
The null and alternative hypotheses are,
H0 : mean = 38
H1 : mean > 38
Using TI-83 plus calculator we get,
p-value = 0.0580
