A market researcher for an automobile company suspects differences in preferred color between male and female buyers.Advertisements targeted to different groups should take such differences into account, if they exist. The researcher examines the mostrecent sales information of a particular car that comes in three colors. (You may find it useful to reference the appropriate table: chi-square table or F table)Sex of Automobile BuyerFemaleColorMaleSilver477298Black536308Red482348a. Choose the competing hypotheses to determine whether color preference depends on the automobile buyer's sex.O Ho Color preference is independent of the automobile buyer's sex.; HA: Color preference is dependent on the automobilebuyer's sex.O Hợ Color preference is dependent on the automobile buyer's sex; HA: Color preference is independent of the automobilebuyer's sex.b-1.

A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. According to the manufacturer, bags should contain an equal number of each color. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim. They opened a bag of candy and recorded the number of candies of each color. The results are shown in the following table. Red Green Blue Yellow Orange 17 24 20 25 14 Which color contributes most to the chi-square test statistic? Red A Green B Blue C Yellow D Orange
An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

One research study of illegal drug use among 12- to 17-year-olds reported a decrease in use (from 11.4% in 1997) to 9.89.8% now. Suppose a survey in a large high school reveals that, in a random sample of 1 comma 0551,055 students, 9595 report using illegal drugs. Use a 0.05 significance level to test the principal's claim that illegal drug use in her school is below the current national average.

From each subgroup of the 12-year-old age group, 7 patients were randomly selected, and they were treated with medications A, B, C, D, E, F, and G. At the end of the treatment, patients who responded positively to the treatment were evaluated as "1," and those who did not respond positively were evaluated as "0." Please interpret the SPSS output.
According to Johns Hopkins Medicine, the healthcare providers consider a fever to be 100.4◦F. Data was acquired in a health center that observed 24 adults with COVID- 19. We want to find out if the sample mean of 104◦F body temperature of adults with COVID-19 is significantly higher than the body temperature of a person with fever. Consider the sample SD of 10.2◦F.
Kindlt 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 test
A researcher selects a sample of 100 people to investigate the relationship between gender (male/female) and registering to vote. The sample consists of 40 females, of whom 30 are registered voters, and 60 males, of whom 40 are registered voters. If these data were used for a chi-square test for independence, what is the observed frequency for registered males?

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 92% of patients taking the drug are healed within 8 weeks. In clinical trials, 210 of 226 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturers claim at the a=0.05 level of significance
A pharmacist claims that more than 60% of all customers simply collect a prescription. One of her assistants notes that in a random sample of 12 customers, 10 simply collected a prescription. Does this provide sufficient evidence to support the pharmacist’s claim? Evaluated on a TI 83 calculator
Historically, the proportions of all Caucasians in the United States with blood phenotypes A, B, AB, and O are .41, .10, .04, and .45, respectively. To determine whether current population proportions still match these historical values, a random sample of 200 American Caucasians were selected, and their blood phenotypes were recorded. The observed numbers with each phenotype are given in the following table.ABABO89181281Is there sufficient evidence, at the .05 level of significance, to claim that current proportions differ from the historic values?a) State the hypotheses.b) Find the critical value at the 5% significance level (rounded off to four decimals).c) Calculate the value of the Chi-square test (rounded off to two decimals).d) State the conclusion at the 5% significance level
