Question

Consider testing Upper H 0 : mu equals 20H0: μ=20 against Upper H Subscript a Baseline : mu less than 20Ha: μ<20 where μ

is the mean number of latex gloves used per week by all hospital employees, based on the summary statistics n=43, x=19.3, and s=11.1

Complete parts a and b.

a. Compute the p-value of the test.

b. Compare the p-value with α=0.05 and make the appropriate conclusion. Choose the correct answer below.

There is sufficient evidence to reject H0

There is insufficient evidence to reject H0

Answer #1

a) test statistic

= -0.414

df = 43 - 1 = 42

p-value = P(t_{42} < -0.414) = 0.3105

b) since p-value is not less than α, we should not reject H0

Option-B) There is insufficient evidence to reject H0

Consider testing Upper H 0 : mu equals 20H0: μ=20 against Upper
H Subscript a Baseline : mu less than 20Ha: μ<20 where muμ is
the mean number of latex gloves used per week by all
hospitalemployees, based on the summary statistics nequals=46, x
overbarxequals=19.3 and sequals=11.3 Complete parts a and b.

Consider testing H0: μ=20 against Ha: μ<20 where μ is the
mean number of latex gloves used per week by all hospital
employees, based on the summary statistics n=43, overbar x = 19.1,
and s=11.2 Complete parts a and b.
a. Compute the p-value of the test.
The p-value of the test is .2991. (Round to four
decimal places as needed.)
b. Compare the p-value with α=0.01 and make the appropriate
conclusion. Choose the correct answer below.
a)There is sufficient evidence...

Consider testing H0: μ=20 against Ha: μ<20 where μ is the
mean number of latex gloves used per week by all hospital
employees, based on the summary statistics n=45, x=19.3, and
s=11.1
Complete parts a andb.
a. Compute the p-value of the test.
The p-value of the test is ?
(Round to four decimal places as needed.)

Given Upper H 0 H0: mu μ equals =25, Upper H Subscript a Ha:
mu μ not equals ≠25, and P equals = 0.023 0.023. Do you reject or
fail to reject Upper H 0 H0 at the 0.01 level of significance?

In a test of the hypothesis
Upper H 0 : mu equals 53H0: μ=53
versus
Upper H Subscript a Baseline : mu greater than 53Ha:
μ>53,
a sample of
n equals 100n=100
observations possessed mean
x overbarxequals=52.452.4
and standard deviation
sequals=3.53.5.
Find and interpret the p-value for this test.

In a test of the hypothesis Upper H 0 : mu equals 10 versus
Upper H Subscript a Baseline : mu not equals 10 a sample of n=50
observations possessed mean x over=10.6 and standard deviation
s=2.7. Find and interpret the p-value for this test.

In a test of H0: LaTeX: \mu μ = 10.8 against LaTeX: H_A H A :
LaTeX: \mu μ < 10.8, the sample data with sample size 20 from a
normal distribution yielded a test statistic Tobs = -2.09. Bracket
the p-value for the test.
Group of answer choices
A) 0.01 < p-value < 0.025
B) 0.05 < p-value < 0.10
C) 0.01 < p-value < 0.005
D) 0.025 < p-value < 0.05

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

Assume that you have a sample of n 1 equals 5, with the sample
mean Upper X overbar 1 equals 48, and a sample standard deviation
of Upper S 1 equals 6, and you have an independent sample of n 2
equals 4 from another population with a sample mean of Upper X
overbar 2 equals 30 and the sample standard deviation Upper S 2
equals 7. Assuming the population variances are equal, at the 0.01
level of significance, is...

(a) Write the claim mathematically and identify
Upper H 0H0
and
Upper H Subscript aHa.
(b) Find the critical value(s) and identify the rejection
region(s). (c) Find the standardized test statistic. (d) Decide
whether to reject or fail to reject the null hypothesis.In a sample
of
10001000
home buyers, you find that
431431
home buyers found their real estate agent through a friend.
At
alphaαequals=0.020.02,
can you reject the claim that
4040%
of home buyers find their real estate agent...
