A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. He wants to construct the 85% confidence interval with a maximum error of 0.12 reproductions per hour. Assuming that the mean is 6.8 reproductions and the variance is known to be 4.84, what is the minimum sample size required for the estimate? Round your answer up to the next integer.

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
