a) Test statistic 
= 1.2
P-value = P(Z > 1.2) = 1 - P(Z < 1.2) = 1 - 0.8849 = 0.1151
b) Test statistic 
= 2.512
P-value = 2 * P(t50 > 2.512) = 2 * 0.0076 = 0.0152
c) Test statistic
= 2.512
P-value = 2 * P(Z > 2.51) = 2 * (1 - P(Z < 2.51)) = 2 * (1 - 0.9940) = 0.012

a. A random sample of 25 is taken from a normal
distribution with population mean = 62, and population standard
deviation = 7. What is the margin of error for a 90% confidence
interval?

Consider a sample of size 22 taken from a normal population. The
sample mean is 2.777 and the sample standard deviation is 0.13. We
test Ho: μ = 2.7 versus H1: μ > 2.7 at the
α = 0.05 level. The rejection region and our decision are
Select one:
a. t > 1.721; REJECT Ho
b. t > 2.080; REJECT Ho
c. t > 2.074; REJECT Ho
d. t > 1.717; REJECT Ho

a. Calculate the expected value and the
standard error for the sampling distribution of the sample mean.
(Negative values should be indicated by a minus sign. Round
"expected value" to 1 decimal place and "standard error" to 4
decimal places.)

A sample of n = 15 observations is taken from a normal
population with unknown mean and variance. The sample has a mean of
¯x = 88.1 and standard deviation 14.29. The researcher hypothesizes
that (a) the population has a mean of 90 and (b) the population has
a variance of 300. Using confidence intervals, determine the
validity of the researcher’s hypotheses at an overall confidence
level of 95% assuming the two confidence intervals are independent.
That is, recalling that...
