A researcher wanted to study if the rate of obesity in a given village was the same as the global rate. She collected data from a random sample of 150 adults and found 14 of the adults in the sample were obese. It is claimed that 13% of adults globally are obese. (a) State an appropriate null and alternative hypotheses for the study. (b) Using a 5% significance level, obtain the test statistic for the hypothesis you proposed for part (a), clearly stating any assumptions you have made. (c) The exact p-value associated with the hypothesis for the study is 0.186. What should the researcher’s conclusion be based on this value?
