hi how do you get the t value in the cal ti83 Test the indicated claim about the means of two populations. Assume that the two samples are independent and that they have been randomly selected. 3) Two types of flares are tested for their burning times (in minutes) and sample results are 3 given below.

3. Test the indicated claim about the means of two populations. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use the P-value method. A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure, measured in mm Hg, by following a particular diet. Use a significance level of 0.01 to test the claim that the treatment group is...
Assume that the assumptions and conditions for inference with a two-sample t-test are met. Test the indicated claim about the means of the two populations. State your conclusion.A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet. Use the sample data below to test the claim that the treatment population mean μ1 is smaller than the control population mean μ2. Test the claim using a significance level of 0.01. Treatment...

Test the indicated claim about the means of two populations. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use the traditional method or P-value method as indicated. A researcher was interested in comparing the response times of two different cab companies. Companies A and B were each called at 50 randomly selected times. The calls to company A were made independently of the...
Construct the indicated confidence interval for the difference between the two population means. Assume that the assumptions and conditions for inference have been met. A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet. Use the sample data below to construct a 99% confidence interval for μ1-μ2, where H1 and H2 represent the population means for the treatment group and the control group, respectively. Treatment GolGroup n1 85 n2...
