Blood nicotine levels in regular cigarette smokers have a mean of 100 mg with a standard deviation of 15 mg. A smoking researcher investigates whether e-cigarettes have positive or negative effect on blood nicotine levels. He gave e-cigarettes to a random sample of 30 smokers and found a mean nicotine level of 140 mg. Test the hypothesis that e-cigarettes had an effect. Please show all the steps involved in a hypothesis testing including proper statistical symbols, formula used, and report/interpret results in complete sentences.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
