Determine if the conditions required for the normal approximation to the binomial are met. If so, calculate the test statistic, determine the critical value(s), and use that to decide whether there is sufficient evidence to reject the null hypothesis or not at the given level of significance.
H0 : p=0.85
H1 : p ≠ 0.85
p̂ =0.778
n=128
α =0.05
a. Calculate the test statistic.
z=
Round to two decimal places if necessary
Enter 0 if normal approximation to the binomial cannot be used
b. Determine the critical value(s) for the hypothesis test.
- +
Round to two decimal places if necessary
Enter 0 if normal approximation to the binomial cannot be used
c. Conclude whether to reject the null hypothesis or not based on the test statistic.
i) Reject
ii) Fail to Reject
iii) Cannot Use Normal Approximation to Binomial

For one binomial experiment, n1 = 75 binomial trials produced r1 = 60 successes. For a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 85 successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ. (a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.) (b) Check Requirements: What distribution does the sample test statistic follow? Explain....

Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 cases of correct results. Use a 0.01 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial...

A recent broadcast of a television show had a 1010 share, meaning that among 60006000 monitored households with TV sets in use, 1010 % of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser that among the households with TV sets in use, less than 1515 % were tuned into the program. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses...

When 3014 adults were surveyed in a poll, 79% said that they use the Internet. Is it okay for a newspaper reporter to write that "3/4 of all adults use the Internet"? Why or why not? Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Identify the null and alternative hypotheses. Choose...

Required information [The following information applies to the questions displayed below.] A recent national survey found that high school students watched an average (mean) of 6.6 DVDs per month with a population standard deviation of 1.00 hour. The distribution of DVDs watched per month follows the normal distribution. A random sample of 30 college students revealed that the mean number of DVDs watched last month was 6.00. At the 0.05 significance level, can we conclude that college students watch fewer...
