Part 1) Given H_{a}: p < 0.20, for which confidence
interval should you reject H_{0}?

Part 2) In another test of H_{0}: μ = 40 against
H_{a}: μ ≠ 40, the sample data yielded the test statistic z
= 2.01. Find the p-value for this test. Round your answer to 4
decimal places.

Given Ha: p > 0.20, for which confidence interval
should you reject H0?

Given Ha: p > 0.20, for which confidence interval should you
reject H0?

Consider the following hypothesis test.
H0: p = 0.20
Ha: p ≠ 0.20
A sample of 400 provided a sample proportion
p = 0.185.
(a)
Compute the value of the test statistic. (Round your answer to
two decimal places.)
(b)
What is the p-value? (Round your answer to four decimal
places.)
p-value =
(c)
At
α = 0.05,
what is your conclusion?
Do not reject H0. There is sufficient
evidence to conclude that p ≠ 0.20.Reject

For a test of H0: p = 0.33 vs. Ha: p ≠ 0.33, the sample of size
101 shows 47 successes. Find the z test statistic. Round to two
decimal places

Consider the following hypotheses:
H0: μ = 6,200
HA: μ ≠ 6,200
The population is normally distributed with a population standard
deviation of 700. Compute the value of the test statistic and the
resulting p-value for each of the following sample
results. For each sample, determine if you can "reject/do not
reject" the null hypothesis at the 10% significance level.

table: z table or t
table) (Negative values should be
indicated...

Consider the following hypothesis test.
H0: μ ≥ 20
Ha: μ < 20
A sample of 50 provided a sample mean of 19.3. The population
standard deviation is 2.
(a)
Find the value of the test statistic. (Round your answer to two
decimal places.)
(b)
Find the p-value. (Round your answer to four decimal
places.)
p-value =

Using
α = 0.05,
state your conclusion.
Reject H0. There is sufficient evidence to
conclude that μ < 20.Reject H0.
There is...

Consider the following hypothesis test.
H0: p = 0.30
Ha: p ≠ 0.30
A sample of 500 provided a sample proportion
p = 0.275.
(a)
Compute the value of the test statistic. (Round your answer to
two decimal places.)
(b)
What is the p-value? (Round your answer to four decimal
places.)
p-value =
(c)
At
α = 0.05,
what is your conclusion?
Do not reject H0. There is sufficient
evidence to conclude that p ≠ 0.30.Do not reject
H0. There...

Consider the following hypotheses:
H0: μ = 9,100
HA: μ ≠ 9,100
The population is normally distributed with a population standard
deviation of 700. Compute the value of the test statistic and the
resulting p-value for each of the following sample
results. For each sample, determine if you can "reject/do not
reject" the null hypothesis at the 10% significance level.

Consider the following hypotheses:
H0: μ = 1,800
HA: μ ≠ 1,800
The population is normally distributed with a population standard
deviation of 440. Compute the value of the test statistic and the
resulting p-value for each of the following sample
results. For each sample, determine if you can "reject/do not
reject" the null hypothesis at the 10% significance level.

Use a t-test to test the claim about the population mean μ at
the given level of significance α using the given sample
statistics. Assume the population is normally distributed.
Claim: μ ≠ 24; α=0.10 Sample statistics: x overbar =
21.4, s = 4.2 , n equals = 11
