Answer:
Fatima's unit rate is 9.5 minutes per mile.
Step-by-step explanation:
To compute the one unit value of a variable divide the total values of <em>n</em> variables by <em>n</em>.
It is provided that it took Fatima 19 minutes to run 2 miles.
Then the unit rate at which Fatima runs is:
Thus, Fatima's unit rate is 9.5 minutes per mile.
We should first calculate the average number of checks he wrote per day. To do that, divide 169 by 365 (the number of days in a year) and you get (rounded) 0.463. This will be λ in our Poisson distribution. Our formula is
. We want to evaluate this formula for X≥1, so first we must evaluate our case at k=0.
To find P(X≥1), we find 1-P(X<1). Since the author cannot write a negative number of checks, this means we are finding 1-P(X=0). Therefore we have 1-0.3706=0.6294.
There is a 63% chance that the author will write a check on any given day in the year.<em />
