Consider testing Upper H 0 : mu equals 20 against Upper H Subscript a Baseline : mu less than 20 where mu is the mean number of latex gloves used per week by all hospital employees, based on the summary statistics nequals41, x overbarequals19.3, and sequals11.2. Complete parts a and b.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
