A large city's DMV claimed that 80% of candidates pass its
new driving tests. Suspecting
that the DMV is inflating its
claims, a local newspaper
conducts a survey of 90
randomly selected local teens
who had taken the test and finds
that only 61 had passed. To test
the plausibility of the survey, the
newspaper runs a simulation of
500 samples of 90 teens from a
population in which 80% passed
the test. The mean and standard
deviation of the resulting
sampling distribution were 0.789
and 0.039, respectively.

step-by-step explanation: i dont

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
