According to researchers, the mean length of imprisonment for motor-vehicle-theft offenders in a nation is 16.6 months. One hundred randomly selected motor-vehicle-theft offenders in a city in the nation had a mean length of imprisonment of 17.3 months. At the 10% significance level, do the data provide sufficient evidence to conclude that the mean length of imprisonment for motor-vehicle-theft offenders in the city differs from the national mean? Assume that the population standard deviation of the lengths of imprisonment for motor-vehicle-theft offenders in the city is 4.0 months. Set up the hypotheses for the one-mean z-test. Hoi Ha: H (Type integers or decimals. Do not round.) The test statistic is z =. (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) the null hypothesis. The data motor-vehicle-theft offenders in the city is sufficient evidence to conclude that the mean length of imprisonment for the mean length of imprisonment for motor-vehicle-theft offenders in the nation.
