Question

according to the cdc, the average weight of men in 1990 was 181 pounds. consider a claim that the average weight of men increased by 2014. (https://abcnews.go.com/health/average - weight - american - men - 15 - pounds - 20 - years/story?id = 41100782) use these hypotheses: $h_0:mu = 181$, $h_a:mu>181$. if you fail to reject the null hypothesis, then your conclusion would be: there is sufficient evidence to warrant rejection of the null hypothesis and to support the claim that the average weight of men increased. there is not sufficient evidence to warrant rejection of the null hypothesis that the average weight of men is the same.

Explanation:

Failing to reject the null hypothesis means that the data does not provide enough evidence to support the alternative hypothesis. Here, the null hypothesis $H_0:\mu = 181$ and alternative $H_a:\mu>181$. So, lack of rejection implies lack of evidence for the claim that the average weight increased.

Answer:

There is not sufficient evidence to warrant rejection of the null hypothesis that the average weight of men is the same.
