A researcher is interested in finding a 95% confidence interval for the mean number minutes students are concentrating on their professor during a one hour statistics lecture. The study included 96 students who averaged 37.1 minutes concentrating on their professor during the hour lecture. The standard deviation was 13.6 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean minutes of concentration is between and...

The primary factor that determines the statistical test students should use is the number of independent and dependent variables. True or False When investigating the relationship between two or more quantitative variables, chi-square is the appropriate test.True or False The Pearson correlation coefficient measures the association between two quantitative variables, distinguishing between the independent and dependent variables.True or False Multiple regression is used when there are several dependent variables and one independent quantitative variable.True or False When testing for the...
A random sampling of the IQ level of 100 students from Texas A&M and 100 students from Harvard results in the following two-sided confidence intervals at a 95% confidence level: Texas A&M students 130 < μ <140 Harvard students 110 < μ <120 Is it possible that the true average IQ of Harvard students is greater than the average IQ of Texas A&M students? True False QUESTION 2 An instructor of an extremely large class (1000 students) starts grading an...
A researcher is interested in finding a 95% confidence interval for the mean number of times per day that college students text. The study included 141 students who averaged 25.7 texts per day. The standard deviation was 21.2 texts. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a tv distribution. 0 and b. With 95% confidence the population mean number of texts per day is between texts. c. If many groups of 141...
