A marketing research company desires to know the mean consumption of milk per week among males over age 2626. A sample of 21722172 males over age 2626 was drawn and the mean milk consumption was 2.42.4 liters. Assume that the population standard deviation is known to be 1.31.3 liters. Construct the 98%98% confidence interval for the mean consumption of milk among males over age 2626. Round your answers to one decimal place.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
