Suppose a recent random sample of employees nationwide who have a 401(k) retirement plan found that 22% of them had borrowed against it in the last year. A random sample of 100 employees from a local company who have a 401(k) retirement plan found that 19 had borrowed from their plan. Based on the sample results,i it possible to conclude, at the a = 0.10 level of significance, that the local company had a lower proportion of borrowers from its 401(k) retirement plan than the 22% reported nationwide? Identify the null and alternative hypotheses for this test. Let p be the population proportion of employees from the local company who borrowed against his or her 401(k) retirement plan in the last year. O A. Ho: p=0.22 HA: p#0.22 O B. Ho:p<0.22 HA: p20.22 OC. Ho: ps0.22 HA:p>0.22 O D. Ho: p20.22 HA:p<0.22 Perform the test using a normal approximation. Identify the test statistic. (Round to two decimal places as needed.) Identify the p-value. (Round to three decimal places as needed.)

A cellphone provider wants to determine the proportion of subscribers who would upgrade to a new cellphone with improved features if it were made available at a substantially reduced cost. Data are collected from a random sample of 500 subscribers. The results indicate that 135 of the subscribers would upgrade to a new cellphone at a reduced cost. At the 0.05 level of significance, is there evidence that more than 20% of the customers would upgrade to a new cellphone at a reduced cost?
Historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous six months, in a sample of 115 new car buyers, 46 have traded in their old car. To determine (at the 10% level of significance) whether the proportion of new car buyers that trade in their old car has this is statistically significantly decreased, what can you conclude concerning the null hypothesis? A) reject the null hypothesis Or B) fail to reject the null hypothesis

According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.33.Suppose a random sample of 109 traffic fatalities in a certain region results in 47that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=0.05 level of significance?
A large manufacturing company investigated the service it received from its suppliers and discovered that, in the past, 41% of all material shipments were received late. However, the company recently installed a just-in-time system in which suppliers are linked more closely to the manufacturing process.A random sample of 150 deliveries since the just-in-time system was installed reveals that 29 deliveries were late. If we want to test whether the proportion of late deliveries was reduced significantly at α = 0.10. Calculate the null and alternative hypothese.
A large manufacturing company investigated the service it received from its suppliers and discovered that, in the past, 44% of all material shipments were received late. However, the company recently installed a just-in-time system in which suppliers are linked more closely to the manufacturing process. A random sample of 170 deliveries since the just-in-time system was installed reveals that 34 deliveries were late. If we want to test whether the proportion of late deliveries was reduced signicantly at = 0:01 the null and alternative hypotheses are a. Null hypothesis (H0) b. Alternative hypothesis (HA)
The manufacturer of a spot remover claims that hisproduct removes 90 percent of all spots. If, in a random sample, only 174 of 200 spots were removed with the man-ufacturer’s product, test the null hypothesis θ = 0.90 against the alternative hypothesis θ < 0.90 at the 0.05level of significance.
In 2016, the US Department of Agriculture established a “maximum acceptable” salmonella prevalence of 15.4 percent for chicken parts sampled at the end of a slaughterhouse’s kill line. 54 of the 154 largest chicken-slaughter facilities in the US failed to meet this standard in 2018. Assume that these results are representative for all large chicken-slaughter facilities. Suppose that in a random sample of 60 chicken parts from the large ACME chicken-slaughter facility (which produces 1,000,000 chicken parts per year), 45 chicken parts test negative for salmonella. c) Estimate the number of chicken parts that are needed for a follow-up study with 90% power to test thenull hypothesis that the prevalence of salmonella among chicken parts at the ACME facility is equal to the maximum acceptable value.

In a clinical trial, 24 out of 880 patients taking a prescription drug daily complained of flulike symptoms.Suppose that it is known that 2.3% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.3% of this drug's users experience flulike symptoms as a side effect at the α=0.01 level of significance?

A recent study at a local college claimed that the proportion, p, of students who commute more than 15 miles to school is no more than 20%. If a random sample of 275 studentsat this college is selected, and it is found that 71 commute more than 15 miles to school, can we reject the colleges claim at the 0.1 level of significance?
