Answer:
Sample mean
Sample variance
Sample proportion
Step-by-step explanation:
Divide 5.00 by 1.5 and you get (it's pretty long) 3.3333333333333333333333333333333
To evaluate the probability that a randomly selected day will be between 28 and 34 minutes we proceed as follows:
P(28<x<34)
First we evaluate the z-score for the above values:
z=(x-σ)/μ
μ=26.7
σ=5.1
when:
x=28
z=(28-26.7)/5.1
z=0.26
P(z<0.26)=0.6026
when x=34
z=(34-26.7)/5.1
z=1.43
P(z<1.43)=0.9236
hence:
P(28<x<34)=0.9236-0.6026=0.321~32.1%
Answer:
Subtract two from 8, the remainder is x. In this case, it is 6.
For future questions, try to think of x as a mystery number rather than a letter. You got this. :)
