- A study of doctor visits examined the relationship between the city of residence and whether or not the patient visited the doctor every year for a checkup. Group 1: In a random sample of 60 Winnipegers, 43 visited the doctor every year. Group 2: In a random sample of 350 Brandonites, 186 visited the doctor every year. At the 5% level of significance, is there a difference in yearly doctor visting between Winnipegers and Brandonites? Note: Be sure to use at least four decimal places in all intermediate calculations. Check that the assumptions and conditions required for this test are met by verifying: Independent Groups Assumption: Met O Not Met. Independence Assumption, checked by the Randomization Condition: OMet ONot Met.arrow_forwardSuppose that a recent report from the Current Population Survey (CPS) of the United States Census Bureau states that 46% of Americans say that now is a good time to find a quality job. Cory works for the mayor's office in a medium-sized city in Texas. The mayor would like to be able to state that the proportion of people in his city are more optimistic about job prospects than people are nationwide and has asked Cory to conduct a study. To test this claim, Cory forms the following null and alternative hypotheses. Ho: P = 0.46 H₁: p > 0.46 The variable p represents the proportion of people in his city who state that now is a good time to find a quality job. The alternative hypothesis, H₁, represents his claim that the proportion of people in his city who state that now is a good time to find a quality job is greater than 46%. To see if his assumption is correct, Cory randomly selects 500 residents of his city. His results are displayed.

- A auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 264 customers found that 30.1% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 326 customers that 22.4% had to return after an appointment. You want to conduct an analysis to determine if there has been an increase in the proportion of customers that need to return after an appointment since the past year, with a = 0. 10. Using this information, what is the critical value of your analysis? Round your final answer to two decimal places. 2.11 1.96 2.33 1.28 1.64arrow_forward3. The production manager of a radio company learned about the kp rule. He used past inspection data concerning the proportion of defective radio speakers purchased per day to construct a p chart with variable sample size. The p chart indicated that the incoming stream of radio speakers was stable with respect to the fraction of defective radio speakers purchased each day. The average fraction of defective radio speakers was found to be 0.002. Further study showed that it costs approximately $0.50 to inspect an incoming radio speaker and that it costs approximately $7.50 to repair a radio with a defective speaker before it leaves the factory. Use the kp rule to determine if 0 percent of 100 percent inspection should be used for incoming radio speakers.arrow_forwardKindlt assist with the question below. An epidemiologist who is working in Capricorn Department of Health investigated the occurrence ofCOVID-19 disease during winter season and found 275 COVID-19 cases out of 10,000 residents ofthe district. Based on these collected data, he would like to proof the claim that "during winter seasonthe proportion of patients with COVID-19 in Capricorn district is less than 3%". Using 5% level ofsignificance, write and test the above claim, following a) wald testarrow_forward
- An auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 402 customers found that 22.4% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 319 customers that 25.1% had to return after an appointment. You want to conduct an analysis to determine if there has been an increase in the proportion of customers that need return after an appointment since the past year, with a significance level of 10%. Using this information, what is the p of your analysis, accurate to three decimal places? 0.286 0.223 0.236arrow_forwardA new quality-inspection program is being tested to see if it will reduce the proportion of parts shipped out that are defective. Under the old program, the proportion of defective parts was 0.10. Two hundred parts that passed inspection under the new program will be sampled, and the number of defectives will be counted. The new program will be implemented if it is shown that the proportion of defectives is less than 0.10.arrow_forwardA sous chef aims to know whether the tenderness of a cooked meat is affected by the way it was prepared (quick roast or square roast) and presented (sliced or cubes). A loin of muscles was cut from 6 different carcasses and each of these muscles were cut into two roasts: (1) quick roast (longer in length and shorter in width), and (2) square roast (same width and length). Six slices and six cubes were removed from each roast. Both were cooked with the same temperature on the same day in ovens with the same model. One cube and one slice from each roast was served and to be rated by six panelists for initial tenderness. The judges then rated all the roast types and serving method and the average score over all 6 judges for each sample was obtained. Below shows the results from jamovi Ⓒ.

- An air conditioning unity company stockpiles air conditioning units in a large warehouse for shipment to retail stores. Sometimes in handling them the appliances get damaged. Even though the damage may be minor, the company must sell those units at drastically reduced prices. The company goal is to keep the level of damaged machines below 4%. One day an inspector randomly checks 53 air conditioning units and finds that 8 of them are damaged. Is this strong evidence that the warehouse is failing to meet the company goal? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. State the null and alternate hypothesis, and find the z-statistic and the p-valuearrow_forwardBack in April and May of 1985, the Gallup organization conducted a poll to estimate the percentage of Americans who approved of how President Reagan was handling his job. At the 5% significance level, do the data suggest that the percentage of those who approved of Reagan increased from April to May in 1985? Population 1: April p = 795/1528 = 0.5203 Population 2: May p = 840/1528 = 0.5497 Show all your steps, setting up your null and alternative hypothesis.arrow_forward
