The probability that a randomly selected statistics textbook will weigh at most x lbs, the number you computed above and the weight of one textbook, is 0.80. Compute and interpret the z-score associated with this probability.

0.842

Step-by-step explanation:

Give that:

Probability that statistics book will weigh at most x lbs ; this can be expressed as ;

P(x ≤ x)

Hence,

P(Z ≤ x) = 0.8

Hence, the Z score associated with a probability of P(Z ≤ x) = 0.8 can be obtained using a Z probability calculator :

Hence, Zscore = 0.842

Hence, the standardized score the weight is 0.842
