Question

I was able to solve questions 1-3 but need help on 4 and 5.

An online poll asked the following question:
"Do you believe that Bigfoot exists?"
Among the n = 1,523 people surveyed, x = 798 responded "yes". Using an a = 0.01 level of
significance, test the claim that most people believe Bigfoot exists by answer the following
questions.
1. The null hypothesis is that exactly 50% of the population believes that Bigfoot exists.
Họ: p = 0.5
There are three options for the correct alternative hypothesis. Circle the correct one.
H: p < 0.5
H: p + 0.5
Hạ: p>0.5
2. Compute the sample proportion p using the following formula. Round your answer to
three decimal places as necessary.
n= 15a3
X=798
P::0.52396580
%3D
IS33 - 0.52396586
(
P= 0.524
3. Compute the test statistic z by using the following formula. Note that q = 1-p. Round
your answer to three decimal places as necessary.
0.524 - 0.5
O.S (1-0.5
1523
6.024
0.0 1281209
1,873
Z=1.873
4. Compute the P-value for the above test statistic, Is this value more or less than
a = 0.01?
5. Based on your above work, should we reject the null hypothesis or should we fail to
reject the null hypothesis?
