The mean birthweight of an infant is thought to be associated with the smoking status of the mother during the first trimester of pregnancy. Consider the data from mothers divided into four categories according to smoking habits, and the corresponding birthweights of their children.- **Group 1: Mother is a non-smoker (NON):** - Birthweights: 7.5, 6.2, 6.9, 7.4, 9.2, 8.3, 7.6- **Group 2: Mother is an ex-smoker (EX):** - Birthweights: 5.8, 7.3, 8.2, 7.1, 7.8- **Group 3: Mother is a current smoker, smokes less than 1 pack per day (CUR < 1):** - Birthweights: 5.9, 6.2, 5.8, 4.7, 8.3, 7.2, 6.2- **Group 4: Mother is a current smoker, smokes more than or equal to 1 pack per day (CUR ≥ 1):** - Birthweights: 6.2, 6.8, 5.7, 4.9, 6.2, 7.1, 5.8, 5.4Using Stata, test whether the mean birthweights are equal across all four groups at the alpha = 0.05 level.**What are your null and alternative hypotheses?**- H0: μ_i == μ_j for all i and j- HA: μ_i ≠ μ_j for at least one i, jOptions for hypotheses are given as follows:- H0: μ_1 == μ_2 - HA: μ_1 ≠ μ_2- H0: μ_i == μ_j for all i and j - HA: μ_i ≠ μ_j for all i and j- H0: μ_i == μ_j for all i and j - HA: μ_i ≠ μ_j for at least one i, j- No answer text provided.

A marketing firm is doing research for an internet-based company. It wants to appeal to the age group of people who spend the most money online. The company wants to know if there is a difference in the mean amount of money people spend per morith on Internet purchases depending on their age bracket. The marketing firm looked at two age groups, 18-24 years and 25-30 years, and collected the data shown in the following table. Let Population 1 be the amount of money spent per month on internet purchases by people in the 18-24 age bracket and Population 2 be the amount of money spent per month on internet purchases by people in the 25-30 age bracket. Assume that the population variances are not the same.
