Residents of New York state that live near the east end of Lake
Ontario receive large amounts of
winter snowfall, referred to as
"lake-effect" snow. Snowfall
exceeding 6 inches in one day is
not uncommon.
In one city, daily snowfalls in this
range were recorded for one
winter (in inches);
8.6, 9.5, 14.1, 11.5, 7.0, 8.4,9.0,
6.7, 21.5, 7.7, 6.8, 6.1, 8.5, 14.4,
6.1, 8.0, 9.2, 7.1, 10.3, 12.1, 8.3
a) Determine if this data is
normally distributed
b) Find the mean and the standard deviation for this data to the
nearest hundredth.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
