The club members are able to attend the conference on the way to bus driver drives the speed limit for 2 hours when when suddenly the bus breaks down and after half an hour another bus arrived then they travel more slowly than the speed limit for 1 more hour. sketch a graph to represent the bus trip over time

label the intervals on the graph describe the behavior of the function in each interval and tell what it means in the problem situation ​

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.
