Question

In order to test H_{O}: p = 0.59 versus H_{1}: p
< 0.59, use *n* = 150 and x = 78 as your sample
proportion.

Using your TI 83/84 calculator device, find the P-value with the appropriate Hypothesis Test

Use a critical level α = 0.05 and decide to Accept or Reject
H_{O} with the valid reason for the decision.

Answer #1

We used 1-proportion z test to calculate the p-value.

**Step 1:** Selection of 1-PropZTest

**Step 2:** Data entry

Following is screenshot of the p-value calculated using TI 84:

p-value = 0.0407

Since p-value = 0.0407 < α = 0.05, we **Reject
HO**

In order to test HO: µ0 = 40 versus
H1: µ ≠ 40, a random sample of size n = 25 is
obtained from a normal population with a known σ = 6. My x-BAR mean
is 42.3 from my sample.
Using a TI 83/84 calculator, calculate my P-value with the
appropriate Hypothesis
Test.
Use a critical level α = 0.10 and decide to Accept or Reject
HO with the valid reason for the decision.

To test Ho: p = 0.38 versus H1: p < 0.38, a simple random
sample of n = 1122 individuals is obtained. The researcher decides
to test this hypothesis atα = 0.10 level of significance.
Compute the power of the test if the true population proportion
is 0.35.

1. Consider the following hypothesis test: Ho : μ = 15 H1 : μ ≠
15 A sample of 50 provided a sample mean of 15.15. The population
standard deviation is 3. a. Compute the value of the test
statistic. b. What is the p value? c. At α = 0.05, what is the
rejection rule using the critical value? What is your
conclusion?

Suppose that we wish to test H0: µ = 20 versus
H1: µ ≠ 20, where σ is known to equal 7. Also, suppose
that a sample of n = 49 measurements randomly selected
from the population has a mean of 18.
Calculate the value of the test statistic Z.
By comparing Z with a critical value, test
H0 versus H1 at α = 0.05.
Calculate the p-value for testing H0 versus
H1.

The P-value for hypothesis test is shown. Use the
P-value to decide whether to reject Ho when the level of
significance is (a) a=0.01, (b) a=0.05, (c) a=0.10.

A sample of 50 provided a sample mean of 15.15. The population
standard deviation is 3.
a. Compute the value of the test statistic. b. What is the p

critical value? What is your conclusion?

Use the P-value method to test the claim that for the adult
population of one town, the mean annual salary is $30,000. Sample
data are summarized as n = 17, = $22,300 and s =
$14,200. Use a significance level of α = 0.05. Is the
assumption correct?

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. H0: p=0.58 versus H1:
p<0.58 n=150, x=78, α=0.05
1. Is np0 (1 minus p 0) ≥10? Yes or No?
2. Use technology to find the P-value. P-value=
(Round to three decimal places as needed.)

3) For a two-tailed hypothesis using a z-distribution, determine
your decision (reject Ho and accept H1 OR fail to reject Ho) and
the type of error you may have committed for the following
situation. Be sure to draw out your distribution, indicate your
critical region plus the critical values and where each of the
following z-scores fall in that distribution.
a) z = -1.97 with an alpha = 0.05
b) z= +2.00 with an alpha = 0.01
c) z =...
