Question

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.

Answer #1

Solution :

= 20

=19.3

S =11.3

n = 46

This is the left tailed test .

The null and alternative hypothesis is ,

H0 : = 20

Ha : < 20

Test statistic = t

= ( - ) / S / n

= (19.3 - 20 ) / 11.3 / 46

= -0.420

Test statistic = t =-0.420

P-value =0.3382

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...

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.

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?

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...

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.
