Question
The researcher found a new medicine came out that can fatten and make the body healthy. Our group assumed that the mean weight of the customer is 32kg. The researcher asked 30 of our customers and found out that their average weight is 42.4 with a standard deviation of 10.22. Using a 0.05 level of significance, can it be possible that the mean weight of the customer after a year when they tried the medicine is greater than 35kg? Get the following: - Sample size, mean, and deviation - null and alternative hypothesis, confidence level & appropriate test static - deciding whether we accept or reject the null hypothesis and interpreting answer (with graph)
