PG&E states that it has a target power supply of 120 volts. Use the home voltage supply amounts in the Voltage data file to test the claim that the mean is 120 volts. Create a histogram of the home voltage data. Copy and paste your histogram here. Does our assumption of normality appear to be satisfied? Yes No What is your null and alternative? H0: µ = 120, H1: µ ≠ 120 H0: µ ≠ 120, H1: µ = 120...

Refer to the accompanying data table, which shows the amounts of nicotine (mg per cigarette) in king-size cigarettes, 100-mm menthol cigarettes, and 100-mm nonmenthol cigarettes. The king-size cigarettes are nonfiltered, while the 100-mm menthol cigarettes and the 100-mm nonmenthol cigarettes are filtered. Use a 0.05 significance level to test the claim that the three categories of cigarettes yield the same mean amount of nicotine. Given that only the king-size cigarettes are not filtered, do the filters appear...
