A researcher is conducting a chi-square test for independence to evaluate the relationship between gender and preference among three different designs for a new automobile. Each individual in a sample of n = 25 males and n = 25 females selects a favorite design from the three choices. If the researcher obtains a chi-square statistic of χ2 = 6.21, what is the appropriate statistical decision for the test? Select one: a. Reject the null hypothesis with α = .05 but not with α = .01. b. Reject the null hypothesis with either α = .05 or α = .01. c. Fail to reject the null hypothesis with either α = .05 or α = .01. d. Fail to reject the null hypothesis with α = .10.

State the null and alternative hypothesis: 1. An aerobics instructor believes that regular exercise is related to greater mental acuity, stress reduction, high self- esteem, and greater overall life satisfaction. She recruits a random sample of 10 adults to participate in her study. Each subject is asked to fill out a series of questionnaires. The results are as follows. Test for the significant association between regular exercise and each of the different factors. 2. Test for the significant relationship between nurses’ satisfaction and nurses’ efficiency 3. Fifteen students are given a test of a general ability and a Math achievement test with the resulting scores: Test for the significant association between general ability and match achievement
Researchers conducted trials to investigate the effects of color on creativity. Subjects with a. Red background were asked to think of creative uses for a brick; other subjects with a blue background were given the same task. Responses were scored by a panel of judges and results from scores of creativity are given in the accompanying table. Higher scores correspond to more creativity. The researchers make the claim that "blue enhances performance on a creative task". Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. what are the null and alternative hypothesis identify the test statistic ifentify the p value
A behavioral scientist investigated whether there is a significant difference in the percentages of men and women who purchase silver-colored cars. The scientist selected a random sample of 50 men and a random sample of 52 women who had recently purchased a new car. Of the men selected, 16 had purchased a silver-colored car. Of the women selected, 9 had purchased a silver-colored car. Which of the following is the most appropriate method for analyzing the results? A two-sample zz-test for the difference in population proportions A A two-sample zz-test for the difference in sample proportions B A one-sample zz-test for a sample proportion C A one-sample zz-test for a population proportion D A one-sample zz-test for a difference in sample proportions
A fish biologist hypothesizes that the proportion of fish in Lake Ontario that are Black Carp has increased. A study conducted several years ago found that 16% of fish in Lake Ontario were Black Carp. Of 300 randomly sampled fish from Lake Ontario, the biologist finds that 96 are Black Carp. Select from the following the test that best reflects the biologist's hypothesis. O a. HO : p = 0.32 vs. Ha : p =/= 0.32 O b. HO : p = 0.16 vs. Ha : p 0.16 O d. HO : p = 0.32 vs. Ha : p> 0.32 O e. HO : p = 0.16 vs. Ha : p = 0.32
Consider the following randomized controlled experiment to study the effect of a new drug on the heart rate of healthy rats. 5 rats were randomly assigned to one of five doses and the maximum observed decrease in heart rate in one hour was recorded. The data obtained are: From this study it can be said that: Select one: a. Explanatory variable and response variable can be either of the two because the study does not specify. b. nothing can be said c. response variable is Dose and explanatory variable is (DFC) d. explanatory variable is Dose and response variable is (DFC)
Use the following information to answer the question. Researchers want to test whether the color of a vehicle ticketed for speeding has an effect on the amount of the ticket. Four vehicle colors were used for the study--red, white, black, and silver. Thirty vehicles were randomly assigned to each group. Use the output below to answer the question. Choose the correct conclusion for the hypothesis that vehicle color affects the amount of a speeding ticket. Assume all ANOVA test conditions have been satisfied. a) Reject H0. The vehicle color has no effect on the amount of the speeding ticket. b) Fail to reject H0. The vehicle color has no effect on the amount of the speeding ticket. c) Reject H0. The vehicle color has an effect on the amount of the speeding ticket. d) Fail to reject H0. The vehicle color has an effect on the amount of the speeding ticket.
A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.01significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference? Human activity Natural patterns Don't know Male 305 151 41 Female 310 170 43 A. Identify the null and alternative hypotheses.
