Select one A 99% confidence level and a sample size of 50 subjects. A 90% confidence level and a sample size of 50 subjects. A 90% confidence level and a sample size of 300 subjects. A 99% confidence level and a sample size of 300 subjects. 100 quesion Question 6 Not yet answered Points out of A poitical action committee wanted to estimate the proportion of county residents who support a change to the county leash law.
