The nicotine content in c

The nicotine content in c

The nicotine content in cigarettes of a certain brand is normally distributed, with mean(in milligrams) u and standard deviation of 0.1. The brand advertises that the mean nicotine content of its cigarettes is 1.5, but measurements on a random sample of 100 cigarettes of this brand give a mean of 1.53. Is this evidence that the mean nicotine content is actually higher than advertised? To answer this, test the hypothesesHo: u=1.5, Ha:u>1.5at the 5% significance level. You conclude:a) that Ho should be rejectedb) that Ho should not be rejectedc) that Ha should be rejectedd) there is a 5% chance that the null hypothesis is true
