Heart rates were measured in 2 groups of individuals. One group included individuals that had recently had heart attacks. The other group included normal individuals. A t-test was performed. The calculated t = 7.04. The critical t at 7 degrees of freedom was: 2.36. What is the conclusion? significant difference unknown until another t test is calculated no significant difference O unknown until a standard deviation is calculated

Problem #1. The emission rates were measured from a sample of 50 engines. The observed value of the sample mean is 92 and the sample standard deviation was s = 21. It is desired to assess the plausibility that the population mean is 100 or more. You need to set up a hypothesis test for a level of significance of 0.05. For this purpose, you need to state the Null and Alternative hypothesis, define the rejection and non-rejection...

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...
