In what follows use any of the following tests/procedures: Regression, confidence intervals, one-sided t-test, or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval. Open Brain data. SETUP: It is believed that the heavier the person (i. e. larger weight) the larger the brain volume should be. Given the data your job is to confirm or disprove this assertion.1. What test/procedure did you perform?a. One-sided t-testb. Two-sided t-testc. Regressiond. Confidence interval

i use the two sided t-test.

Step-by-step explanation:

it would be nearly impossible to ascertain with certain the proposition above but we would rather guess using the parameters that were available at the time.

generally in statistics, we use a two sided t-test when an area of a distribution is two-sided and tests whether a particular given sample in question  is greater than or less than a exact range of values.

the two sided t-test  is mostly used in null-hypothesis testing and testing for statistical significance.
