The CEO of a large supermarket chain in the region is claimingto be paying its contractual higher than the minimum daily wage rate of Php 500.00 1ocheck on this claim, a labour union leader obtained a random sample of 144 contractuaiemployees from this supermarket chain. The survey of their daily wage earnings resultedto an average wage of Php 510.00 per day with standard deviation of Php 100.00. The dailywage of the region is assumed to follow a distribution with unknown population variance.Perform a test of hypothesis at 5% level of significance to help the labour union leader makean empirical based conclusion on the CEO's claim.General As a do the for works1.

To date, you have learned about statistical significance (rejecting the null hypothesis) and the four major factors that significantly affect it. Please explain why they believe that teaching administrators and other professionals should rely on new and tested methods of school policing that have resulted in a statistically significant decline in parental complaints. Also, explain why it's important that the results be statistically significant.
A research center claims that more than 37% of U.S adults eat breakfast everyday. In a random sample of 300 U.S adults, 123 said they eat breakfast everyday. At 0.10 level of significance, what can you conclude about the researchers claim?
Apple Computer believed that 36 percent of its smartphone customer own the most recent model of iPhone (Ho). To test this hypothesis, it gathered customer data using a CRM software. The results indicated that only 30 percent of the iPhone users owned iPhone 11, the most recent model. Assume that this percentage value was based on a sample of 300 users. Test its hypothesis using 95% confidence level.

A survey conducted on a group of 250 people randomly recruited from among the retirees revealed that 115 people were willing to find a new job. It is known that the rate of those who previously wanted to work among retired people is 67%. Can it be claimed that the ratio of these two tendencies is different from each other for the 2% significance level? Test it, interpret the decision you made as a result of the test. While testing the hypothesis test, apply the 4 stages and show them separately.
The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 53 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: p = 0.77; H1: p = 0.77 O Ho: p 0.77 O Ho: p = 0.77; H1: p 5 and ng > 5. O The standard normal, since np > 5 and ng > 5. The Student's t, since np < 5 and nq < 5. O The standard normal, since np < 5 and ng < 5. What is the value of the sample test statistic? (Round your answer to two decimal places.) (c) Find the P-value of the test statistic. (Round your answer to four decimal places.)
What is the approximate sample size required to estimate the percentage of Americans who have earned a college degree to within 2%, with 95% confidence?
I want to estimate the population mean number of times that adults eat breakfast in a week. I spoke with 12 coworkers, and the numbers were 7, 5, 5, 7, 2, 3, 7, 5, 1, 0, 7, 6. Calculate a 95% confidence interval for the population mean (round 3 decimal places).
The proportion of students who pass a placement exam at a college has been 0.64. With hopes toincrease that proportion the college hired a company to provide a brief refresher class before the test is given.A sample of 250 students got selected for the study and 168 of these students passed the exam. At the 5%significance level do the data provide enough evidence to claim the population proportion of students passingthe test will be higher with the company’s refresher class? what is the hypthesis and test stastic?
Researchers are studying whether the proportion of homeschooled children in district 1 (considered 1) is less than the proportion of homeschooled children in neighboring district 2 (considered as 2). To test the theory info was gathered: district 1 had 600 students of which 90 were homeschooled. District 2 had 550 students of which 99 were homeschooled. What is the 95% confidence interval for the difference proportion between district 1 and 2? A. (-0.086, 0.026) B. (0.143, 0.217) C. (0.113, 0.187)
I believe that the population mean number of times that adults go for a walk each week is less than 2.0. I spoke with 8 adults and found that they went on walks 3,5,2,1,0,4,0 and 5 times last week. Test this hypothesis at the 0.5 significance level.
