Question

The p-value and the value of α for a test of H_{o}: μ =
150 are provided for each part. Make the appropriate
conclusion regarding H_{o.}

- P-value = .217, α = .10
- P-value = .033, α = .05
- P-value = .001, α = .05
- P-value = .866, α = .01
- P-value = .025, α = .01

Answer #1

**Answer:**

Given,

Null hypothesis Ho : μ = 150

Here we compare the p value & level of significance to give the conclusion about the hypothesis.

If p value < α then we reject the Ho , accept Ha

If p value >= α then we fail to reject Ho.

So now,

a)

P value = 0.217 , α = 0.10

Here p value > α . so we fail to reject Ho.

b)

P-value = .033, α = .05

Here p value < α , so reject Ho

c)

P-value = .001, α = .05

Here p value < α , so reject Ho.

d)

P-value = .866, α = .01

Here p value > α , so we fail to reject Ho

e)

P-value = .025, α = .01

Here p value > α , so we fail to reject the null hypothesis Ho.

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?

In a test of the hypothesis Ho: μ = 50
versus Ha: μ ≠ 50,
with a sample of n = 100 has a Sample Mean = 49.4 and Sample
Standard Deviation, S = 4.1.
(a) Find the p-value for the test. (b)
Interpret the
p-value for the test, using
an α =
0.10.

We adopt α=.05 and test the hypothesis Ho: μx=50. What
conclusion should we draw if... (a) n=10, tcalc = +2.10, and Ha: μx
≠ 50? (b) n=20, tcalc = +2.10, and Ha: μx ≠ 50? (c) n=10, tcalc =
+2.10, and Ha: μx > 50? Show the critical value of t for each
part.

Consider a test of H0: μ=75 performed with the computer. The
software reports atwo-tailed p-value of 0.1032.
Make the appropriate conclusion for each of the following
situations.
a Ha:μ<75, z=−1.63,α=0.05
b. Ha:μ<75, z=1.631,α=0.07
c.Ha:μ>75, z=1.63, α=0.07
d. Ha:μ≠75, z=−1.63, α=0.01
a. Choose the correct answer below.
A) There is sufficient evidence to reject H0.
B) There is insufficient evidence to reject H0.

In order to test HO: p = 0.59 versus H1: 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
HO with the valid reason for the decision.

Consider the Ho: μ=45; n=48; s=18; α=5%. Write the
rejection rule for the appropriate test statistic.

Test the following hypotheses by using the χ 2
goodness of fit test.
H 0:
p A = 0.2, p B = 0.4,
and p C = 0.4
Ha:
The population proportions are not
p A = 0.2 , p B = 0.4 ,
and p C = 0.4
A sample of size 200 yielded 40 in category A, 120 in category
B, and 40 in category C. Use = .01 and test to see
whether the proportions are as stated...

You wish to test the following claim (Ha) at a significance
level of α=0.02.
Ho: μ = 83.4
Ha: μ > 83.4
You believe the population is normally distributed, but you do not
know the standard deviation. You obtain a sample of size n=54, with
mean M=85.2, and a standard deviation of SD=11.7.
1. What is the test statistic for this sample? (Report
answer accurate to THREE decimal places.)
test statistic =
2. What is the p-value for this sample?...
