In 2005, Health Canada claimed that 16.5% of Canadian adults are obese. A researcher wanted to check whether this percentage has increased in 2009. He randomly selected 105 Canadian adults and found 22 of them are obese. Write down lower value for 92% confidence interval for percentage of Canadian adults with obesity. Example, if the CI is (1.2,1.8), then the lower value of this Cl is 1.2. Give your answer to 3 decimal places. QUESTION 30 In 2005, Health Canada claimed that 16.3% of Canadian adults are obese. A researcher wanted to check whether this percentage has decreased in 2009. He randomly selected 235 Canadian adults and found 26 of them are obese. Use7% significance level. Null and alternative hypothesis are O HO: mu = 16.3 O H0: p >= 0.163, H1: p = 16.3, H1: mu = 0.163
