Solution-:
Option (1) 3.2 is correct.
Because, For two groups, we can use both t-test and ANOVA and the results would be the same.
Assumptions of both t-test and ANOVA, include normality of response variable for each category of predictor variable, which can be tested by one sample k-s test or Shipro-Wilk test.
Assumptions of both t-test and ANOVA, include homogeneity of variance.
In other words we said that T test is special type of ANOVA that can be used when we have only two populations to compare their means.

Using the t-Test Exercise Data Set Excel file, Look at the date set of Systolic Blood Pressure Normal Weight/Systolic Blood Pressure Obese Write a null hypothesis for the comparison (use the null hypothesis template). Also, write a directional hypothesis that reflects the anticipated outcome. Conduct a t-test two-sample assuming unequal variances using Excel. Interpret the Excel result (was it significant, what was the critical t-value, what was the calculated t-value, what should be done with the null hypothesis—accept or reject)....

ANOVA
A study is designed to examine whether there is a difference in
mean daily calcium intake among three groups of adults with normal
bone density (Norm), adults with osteopenia (OstPNia) (a low bone
density which may lead to osteoporosis) and adults with
osteoporosis (OstPSis). A total of twenty-one adults at age 60 was
recruited in the study (7 adults in each group). Each participant's
daily calcium intake was measured based on reported food intake and
supplements in milligrams. We...

Question 2In one tailed T-test, if the test statistics is \(\mathrm{t}\) and \(\mathrm{t}_{0}\) is the t-value under null hypothesis, then \(\mathrm{p}\) -value \(=\operatorname{Pr}\left(\mathrm{t}<\mathrm{t}_{0} \mid\right.\) null hypothesis is true) if \(\mathrm{t}_{0}>0\) and p-value \(=\operatorname{Pr}\left(t>t_{0} \mid\right.\) null hypothesis is true) if \(t_{0}<0\).Question 3In a recent twin study from researchers at King's College London, the researchers wanted to first test whether identical twins show statistically significantly different thigh muscular power. To test this, they recruited 20 identical female twins. For this analysis,one-way ANOVA...

A study looked at the relationship between alcohol consumption and level of systolic blood pressure (SBP) in women not using oral contraceptives (OC). Alcohol consumption was categorized as follows: no alcohol use; ≤ 10 oz/week alcohol consumption; > 10 oz/week alcohol consumption. The results for the SBP measurements for women 30-39 years of age are given below. Group Mean var n A. No Alcohol Use 105.3 10.6 24 B. ≤ 10 oz/week alcohol consumption 110.4 13.4 12 C. > 10...
