In 1974, ken stabler won the nfl's most valuable player award as the
quarterback for the oakland raiders. during the regular season, he completed
115 of his 194 passes at home and 63 of his 116 passes on the road.
(a) how much better did stabler perform at home in 1974? calculate the
difference in the proportion of completed passes at home and on the road.
(b) calculate a 95% confidence interval for the difference in stabler's ability to
complete a pass at home and his ability to complete a pass on the road.

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

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then
