You are told that a 95% ci for expected lead content when traffic flow is 15, based on a sample of n = 11 observations, is (461.5, 598.3). calculate a ci with confidence level 99% for expected lead content when traffic flow is 15. (round your answers to one decimal place.)

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

false

inverse variation is not exponential
