Question 3: Using Excel, conduct a NHST to determine whether there is a correlation in the population. Use a 0.05 significance level. Use the Excel file Assignment10_R1.xlsx, Exercise1_Correlation NHST worksheet) Alpha 0.05 n 22 df 20 CV t 2.086 r -0.6599 r2 0.4354     t -3.927 p-value 0.00083 Write the Null & Alternate Hypotheses (Follow the examples shown in Clear-Sighted Statistics. Use the appropriate Greek letters and mathematical symbols). H0: H1: 2. Write the Decision Rule using the Critical Value(s), not p-values. 3. Calculate the value of the test statistic and the p-value. 4.What is your decision regarding the Null Hypothesis? Frame your report in the context of this problem

A hospital administrator wants a statistic to calculate the relationship between the degree of patient satisfaction and whether that patient was treated in the ER or admitted to the hospital. one-sample t point-biserial correlation O independent-measures t sign test

Which measure of central tendency would be the most appropriate for this set of data? (3, 8, 1, 6, 3, 4, 11, 3, 4, 3, 5) mode variance mean median

Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support Correlation Results the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that Correlation coeff, r: 0.959614 a measured chest size can be used to predict the weight? Use a significance level of = 0.05. Critical r: +0.2680855 P-value (two tailed): 0.000 Но: Р H1:P (Type integers or decimals. Do not round.) Identify the correlation coefficient, r.

Using the linear correlation coefficient given above, calculate and give the value of the coefficient of determination. Explain in a sentence what this means in the context of this example, treating gpa as a predictor.

Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Use a significance level of x = 0.05 to answer the following questions. Correlation Results Correlation coeff, r: Critical r: P-value (two tailed): 0.000 Identify the correlation coefficient, r. r= (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed.) OA. There are two critical values at r= ± OB. There is one critical value at r= Is there sufficient evidence to support the claim that there is a linear correlation between the weigh of bears and their chest sizes? Choose the correct below and, if necessary, fill in the answer box within your choice. (Round to three decimal places as needed.) exceeds the critical value. A. No, because the absolute value of r= OB. Yes, because the absolute value of r= OC. No, because r= exceeds the positive critical value. falls…
