Y 9.4.87 Question Help According to researchers, the mean length of imprisonment for motor-vehicle-theft offenders in a nation is 15.1 months. One hundred randomly selected motor-vehicle-theft offenders in a city in the nation had a mean length of imprisonment of 16.2 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. Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. Set up the hypotheses for the one-mean z-test. Ho: H = 15.1 Ha: H + (Type integers or decimals. Do not round.) 15.1 The test statistic is z = (Round to two decimal places as needed.)

Y 9.4.87-P Question Help According to researchers, the mean length of imprisonment for motor-vehicle-theft offenders in a nation is 16.7 months. One hundred randomly selected motor-vehicle-theft offenders in a city in the nation had a mean length of imprisonment of 17.9 months. At the 1% 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 8.0 months. Set up the hypotheses for the one-mean z-test.
