We formulate the null and alternative hypothesis here to state that battery life of the laptop lasts at least 12 hours(more than but not less, null hypothesis) or that it lasts less than 12 hours(alternative hypothesis).
The null hypothesis is the one being tested to know whether we would reject it or not in which case we choose the alternative hypothesis. To test the hypotheses, we do a t test using a significance level of say 0.05(95% confidence interval) and find our p value in order to compare and decide if the null hypothesis would be rejected or not based on statistical significance.
The converse of an if statement is a statement in which the hypothesis and conclusion are switched.
<span>You will get into college if you work hard.
The "if" part is the hypothesis.
The "then" part is the conclusion.
Rewrite the original if statement in the if-then form:
If you work hard, then you will get into college.
The hypothesis is the if part: "you work hard"
The conclusion is the then part: "you will get into college"
To write the converse, switch the hypothesis and the conclusion.
If you get into college, then you worked hard.
This happens to be choice A.
