Answer:
And replacing we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size selected
represent the population proportion
We want to find the standard error and we can use the distribution for the sample proportion and for this case since the sample size is large enough and we satisfy np>10 and n(1-p) >10 we have:
And the standard error is given;
And replacing we got:
10 minutes is 1/6 of an hour.
1 hour and 10 minutes = 7/6 hours
98 km / 7/6 = 98 x 6/7 = (98 x 6) /7 = 588/7 = 84 km per hour
