Question

The claim is that for a smartphone carrier's data speeds at airports, the mean is μ=18.00 Mbps. The sample size is n=1717 and the test statistic is t=−1.976.

Answer #1

se technology to find the P-value for the hypothesis test
described below.
The claim is that for a smartphone carrier's data speeds at
airports, the mean is
muμequals=16.00
Mbps. The sample size is
nequals=14
and the test statistic is
tequals=negative −2.404.
P-valueequals=nothing
(Round to three decimal places as needed.)

Use
technology to find the P-value for the hypothesis test described
below.
The claim is that for a smartphone carrier’s data speeds at
airports, the mean is u= 14 mbps. The sample size is n=18 and the
test statistic is t= -2.055.

Will give thumbs up for correct answer.
Researchers measured the data speeds for a particular smartphone
carrier at 50 airports. The highest speed measured was
72.2 Mbps. The complete list of 50 data speeds has a mean of x
=16.02 Mbps and a standard deviation of s=30.03 Mbps.

The display provided from technology available below results
from using data for a smartphone carrier's data speeds at airports
to test the claim that they are from a population having a mean
less than 6.00 Mbps. Conduct the hypothesis test using these
results. Use a 0.050 significance level. Identify the null and
alternative hypotheses, test statistic, P-value, and state the
final conclusion that addresses the original claim.
