Arandom sample of 225 items from a population results in 60% possessing a given characteristic. using this information, the researcher constructs a 99% confidence interval to estimate the population proportion. the resulting confidence interval is

Step-by-step explanation:

The formula for a - level confidence interval for the population proportion:-

Given : n = 225 ; p = 0.60 ;

By using the given information , the confidence interval for the population proportion:-

Hence, the resulting confidence interval is .

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
