Answer: False I'm pretty sure
Step-by-step explanation:
Answer:
38.117%
Step-by-step explanation:
Firstly, what you do is to calculate the z-score of both points
Mathematically;
z-score = (x-mean)/SD
where mean = 70 and SD = 5
For 68, z-score = (68-70)/5 = -2/5 = -0.4
for 73, z-score = (73-70)/5 = 3/5 = 0.6
The probability we are to calculate ranges from
P(-0.4<z<0.6) = P(z<0.6) - P(z<-0.4)
it is at this point that we make use of z score table
= 0.38117 which is 38.117%
