Document Summary
We will conduct a hypothesis test to examine the significance of the restaurant"s claim at the 1% level of significance. A =0. 01: let , set up hypothesis: a. *notice that we phrase the hypotheses in terms of seconds, since our data were measured in seconds. If our p-value is < 0. 01: rejection rule, we will reject , the test statistic is, the p-value is p(t(30) 1. 61) by the symmetry of the t distribution. we see from table d that p(t(30) 1. 310) = 0. 10 and p(t(30) . 1. 697) = 0. 05. since 1. 310 < 1. 61 < 1. 697, it follows that the p-value is between. 0. 05 and 0. 10. for any p-value between 0. 05 and 0. 10, we fail to reject the null hypothesis, so our conclusion is as follows . In 1968, census results indicated that the age at which american men first married had a. What is a 95% confidence interval for the true mean age of first-time grooms in 2008? s.
