In 2011, Marko Tomac and Ivan Cvetkovic set the Guinness World Record for the “Greatest distance driven on a single tank of diesel fuel.” They drove `1,581.88` miles through Croatia in a Volkswagen Passat 1.6 TDI BlueMotion, averaging `76.37` mpg.

In 2011, the average price, in U. S. dollars, for diesel fuel in Croatia was about `\$6.038` per gallon. At the same time, in the United States, the average price for diesel was `64\%` of what it cost in Croatia.

Estimate the cost of one gallon of diesel in the United States in 2011?

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.
