Answer:
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
