Sol:

Quartile function 5 number summary

=QUARTILE(A1:A32,1) --->gives Q1

=QUARTILE(A1:A32,2) --->gives median

=QUARTILE(A1:A32,3) --->gives Q3

Midhinge=Q1+Q3/2

Q1=

=QUARTILE(A1:A32,1)

=17.5

Q2=

=QUARTILE(A1:A32,2)

=25

Q3==QUARTILE(A1:A32,2)

=32.25

midhinge=Q1+Q3/2

=17.5+32.25/2

= 24.875

=24.88

1st quartile=17.5

Median =25

3rd quartile=32.25

Midhinge=24.88

The number of customers that visit a 24-hour local supermarket during the off-peak hours between 8am - 11am is known to be distributed as Poisson with mean 2 per hour. Determine the probability that i. no customers will visit the supermarket between 8am - 9am. ii. exactly one customer will visit the supermarket between 9am - 11am. iii. exactly one customer will visit the supermarket for each of the time intervals 8am - 9am and 9am-11am.
