What to do: Take the two numbers 3 and 15 and put the number of green (3) as the numerator and the number of total colors (15) as the denominator as shown here 3/15 and then you simplify it. How many time does 3 go in to 3, 1 time and how many times does 3 go in to 15, 5 times so it would be 1/5.

Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting for, either North Hig

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
We can calculate P value

Confidence Interval = p ± z $\sqrt{p(1-p)/n}$
