Assume that you plan to use a significance level of alpha = 0.05
to test the claim that p1 = p2. Use the given sample sizes and
numbers of successes to find the z test statistic for the
hypothesis test.

Test the claim about the population mean mu at the level of
significance alpha. Assume the population is normally distributed.
Claim: mu greater than 11; alpha equals0.05; sigmaequals1.2

Conduct a test at the a = 0.05 level of significance by
determining (a) the null and alternative hypotheses (b) the test
statistic (c) the critical value, and (d) the P-value. Assume that
the samples were obtained independently using simple random
sampling.
1. Test whether p1 is not equal to p2.
Sample data: x1 = 804, n1 = 874,
x2 = 902, n2 = 954

You wish to test the following claim (Ha) at a significance
level of α = 0.05.
Ho: μ = 58.9
Ha: μ < 58.9
You believe the population is normally distributed, but you do
not know the standard deviation. You obtain a sample of size n = 34
with mean M = 54.2 and a standard deviation of SD = 8.3.
1. What is the test statistic for this sample? (Report
answer accurate to THREE decimal places.)

A) Assume that the significance level is α=0.05. Use the given
information to find the P-value and the critical value(s). The
test statistic of z = −1.09 is obtained when testing the claim that
p<0.2.
B) Identify the type I error and the type II error that
corresponds to the given hypothesis. The proportion of settled
medical malpractice suits is 0.29.
C) A survey of 1,562 randomly selected adults showed that 579 of
them have heard of a new electronic...
