a.express the confidence interval in the format that
uses the "less than" symbol. Given that the original listed data
use one decimal place, round the confidence interval limits
accordingly.

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 5.00 Mbps. Conduct the hypothesis test using these
results. Use a 0.05 significance level. Identify the null and
alternative hypotheses, test statistic,P-value, and state the
final conclusion that addresses the original claim.

The accompanying data on degree of spirituality for a sample of
natural scientists and a sample of social scientists working at
research universities appeared in a paper. Assume that it is
reasonable to regard these two samples as representative of natural
and social scientists at research universities. Is there evidence
that the spirituality category proportions are not the same for
natural and social scientists? Test the relevant hypotheses using a
significance level of 0.01.
