The mean age for young adults to get married is normally distributed with a a mean of 29.8 years and a standard deviation 6.7 years old. What is the probability that a random sample of 45 U. S adults mean age when they were married at most 32 years old? (round to 4 decimal places)

My approach was following: 6.7/√ 45 =0.9987770299. TI-84 calculator, normal CDF: (-1E99, 32, 29.8, 0.9987770299)
Result: 0.9862

Can anyone confirm if this is correct please?

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

step-by-step explanation:

the answer is 89 d
