Answer:

the test I will perform is d. ​​Two-sided t-test

Step-by-step explanation:

When we are to compare between different data, critical regions occur on both sides of the  mean of a normal distribution,they are as a result of two-tailed or two-sided tests.

In such tests, consideration has to be given to values  on both sides of the mean.

for this question, it is expected to compare weather it is true that first born have different intelligent or not, weather to accept a null hypothesis or reject.

For example, if it is  required to show that the percentage of metal, p, in a

particular alloy is x%, then a two-tailed test is used,  since the null hypothesis is incorrect if the percentage  of metal is either less than x or more than x.
