Answer:
70th percentile for the amount of time between customers entering is 30.10
Step-by-step explanation:
given data
mean = 25
to find out
What is the 70th percentile for the amount of time between customers entering Clay's store
solution
we know that here mean is
mean =
..................1
so here 25 =
and we consider time value corresponding to 70th percentile = x
so we can say
P(X < x) = 1 -
P(X < x) = 70 %
1 -
= 70 %
1 -
= 0.70
= 0.30
take ln both side
= ln 0.30
= 1.203973
x = 30.10
70th percentile for the amount of time between customers entering is 30.10
Answer: 0.11
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us <em>.</em>11 or 0<em>.</em>11.
So 11% can be written as the decimal 0<em>.</em>11.
