Question

**Identify the null and alternative hypothesis(in symbolic
and sentence form), test statistic,
P****-****value(or critical values),
conclusion about the null hypothesis, and final conclusion that
addresses the original claim(Don’t just say Reject the null
hypothesis or fail to reject the null hypothesis). If you used the
calculator, identify everything mentioned above in addition to
which calculator functions and inputs for each field were
used.**

According to a recent poll 53% of Americans would vote for the incumbent president. If a random sample of 100 people results in 45% who would vote for the incumbent, test the claim that the actual percentage is 53%. Use a 0.10 significance level.

Answer #1

The null and alternate hypothesis are:

H0:

Ha:

The test statistic is given by:

Since this is a two-tailed test, so the p-value is given by:

Since p-value is greater than 0.10, so we do not have sufficient evidence to reject the null hypothesis H0.

Thus we do not reject H0.

We can conclude that the actual percentage is 53%.

In a 3M Privacy Filters poll, 806 adults were asked to identify
their favorite seat when they fly, and 492 of them chose a window

Identify the null hypothesis, alternative hypothesis, test
statistic, P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. The health of
employees is monitored by periodically weighing them in. A sample
of 54 employees has a mean weight of 183.9 lb. Assuming that ? is
known to be 121.2 lb, use a 0.10 significance level to test the
claim that the population mean of all such employees weights is
less than 200 lb.
