Three consecutive integers: Let the first be x. Then the second would be x+1 and the third would be x+2. The sum of these 3 consecutive integers would then be x + x+1 + x+2, or 3x + 3.

Unless you know what this sum is (numerically speaking), you cannot solve this problem for x.

Answer:

P ( x_bar > 335 ) = 0.9826

Step-by-step explanation:

Given:

- Mean amount u = 350

- standard deviation s.d = 45/year

- Sample size n = 40

Find:

- The probability of sample mean P( x_bar > 335 )

Solution:

- P ( x_bar > 335 ) = P ( Z > sqrt(n)*(x_bar - u)/s.d)

= P ( Z > sqrt(40)*(335-350)/45)

= P ( Z > -2.111) = P ( Z < 2.111)

= 0.5 + P( 0 < Z < 2.111)

= 0.5 + 0.4826

= 0.9826
