1. State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain.
?(a) t=2.201
?(b) t=0
?(c) t=-2.089
?(d) t-2.237
(*****t0 on the graph is positioned to the left at -2.108****)
2. In a survey of 628 males ages? 18-64, 393 say they have gone to the dentist in the past year.
Construct? 90% and? 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.
3. In a random sample of 21 ?people, the mean commute time to work was 31.8 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a? t-distribution to construct a 90?% confidence interval for the population mean μ. What is the margin of error of mμ??
You drive on Interstate 10 from San Antonio to Houston, half the time at 60 km/h and the other half at 105 km/h. On the way back you travel half the distance at 60 km/h and the other half at 105 km/h.
