Perpetrators of a crime who have been given the maximum sentence of 10 years are
believed bya fiscal to have been sentenced to no more than 7 years on the average.
random sample of 20of these crime offenders reveals a mean sentence of 7.6 years with a
standard deviation of 2.4 years. Is the fiscal correct in his suspicions at the 0.05 level of
significance?
Step:
1. State the null and alternative hypothesis
concerning the population mean, "\\mu" and the type of test to be used.
2.Specify the level of significance "\\alpha"
3.State the decision rule
4. Collect the data and perform calculations.
5. Make a statistical decision.
6.State the conclusion
Two trains on separate tracks move toward each other. Train 1 has a speed of 130 km/h; train 2, a speed of 90.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1 when the air temperature is 16oC?
