The test statistic is...............(Round to two decimal places as needed.)
The P-value is.......................(Round to three decimal places as needed.)
The test statistic t is ..................
(Round to three decimal places as needed.)
The P-value is.............................(Round to three decimal places as needed.)
The P-value for this hypothesis test is
0.2300.230.
(Round to three decimal places as needed.)
Q1) The value of the correlation coefficient is
The value of the test static is
The test is two tailed test and number of degrees of freedom is 6-2=4
So P-value is
As P-value is 0.066>0.01
We fail to reject the null hypothesis
There is no relation between the two
Q2)
The value of the correlation coefficient is
The value of the test static is
The test is two tailed test and number of degrees of freedom is 9-2=7
So P-value is
As P-value is 0.003<0.05
We reject the null hypothesis
Q3) The sample proportion is
Value of test static is
The P-value is
The test statistic is...............(Round to two decimal places as needed.) The P-value is.......................(Round to three decimal...
Listed below are amounts of court income and salaries paid to the town justices. All amounts are in thousands of dollars. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using a = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between court incomes and justice salaries? Based on the results, does it appear that justices might profit by levying larger fines? Court Income 64.0 406.0 1566.0 1130.0...

Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6014 patients treated with this drug, 159 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction?
