Conduct a hypothesis test based on the following information using a significance level of 5%: Research Question: do more than 30% of students going to college have student loan debt?   Test statistic = 2.16 sample size = 50  

Using the following information select the appropriate interpretation for the correlation coefficient: Variables being compared are number of years of experience at a job and annual salary. r = -0.01

Select the appropriate interpretation for the slope of the linear regression equation below. Y (Dependent Variable) = Cost of a house in thousands of dollars X (Independent Variable) = number of miles from an elementary school   yhat =  325 – 6*X

Ten students were randomly selected from the College of Public Health and their diastolic blood pressure was tested. The sample mean and standard deviation were 78.2 mmHg and 2.1 mmHg respectively. What is the obtained t-score for this sample under the null hypothesis Ho: µ = 80?

A biostatistician finds the relationship between the number of weeks (X) spent in a hospital and number of seizures per week (Y) and is described by the following equation:. This is based on a sample size of 50 patients and the associated coefficient of correlation is r = -.93. Using this information above, answer the following question: How do you interpret the slope of b1 = -.91?

Conduct a hypothesis test based on the following information using a significance level of 5%: Research Question: Do carpenters earn lower salaries than accountants? Assume the population variances for the two groups are equal to each other Group 1 = Carpenters Group 2 = Accountants Test statistic = -1.65 Group 1 Sample size = 10 Group 2 Sample size = 11

Select the appropriate interpretation for the slope of the linear regression equation below. Y (Dependent Variable) = Cost of a house in thousands of dollars X (Independent Variable) = size of the house in hundreds of square feet   yhat = 10 + 12.3*X

Using the information below calculate the predicted value for Y for the given value of X. Y (Dependent Variable) = Cost of a house in thousands of dollars (i.e. Y = 1 means one-thousand dollars) X (Independent Variable) = size of the house in hundreds of square feet (i.e. X = 1 means one-hundred square feet)   yhat = 10 + 12.3*X   On average how many thousands of dollars will a house cost if it is 15 hundred square feet (round your answer to 4 decimal places)?
