Romashka-Z-Leto [24]

Answer:

B

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}
