Next question Suppose a study reported that the average person watched 4.73 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 1% significance level, do the data provide sufficient evidence to conclude that the amount of television watched per day last year by the average person differed from the value reported in the study? (Note: x-4,093 hours and s-1.391 hours) Set up the hypotheses for the one-mean 1-telt M₂:4 H₂H 3.1 17 26 4.1 46 61 3.5 41 31 29 62 52 38 64 40
Next question 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 17.5 months. At the 5% 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 2-test H₂H H₂H (Type integers or decimals. Do not round)
