In the Annual Health Survey conducted by the British Government, one of the health indicators reported is obesity, a factor that has been viewed with increasing alarm in many western countries. A recent Health Survey reported that in a random sample of 3509 British adults 23% were medically classified as obese (parliament.thestationeryoffice.co.

If the government had set a goal of promoting health measures that would reduce the percentage of obese adults to less than 25%, would these sample results be sufficient to make the case that the government had achieved its goal? Use a 1% significance level. As you proceed,
a. Show the null and alternative hypotheses.
b. Compute the pvalue for the sample result.
c. Use the pvalue from part b to decide whether you will reject the null hypothesis. Explain your decision.
