**Independent t-test**

Use the following data and scenario to answer the questions.

You want to know if someone's exercise status (those who exercise and those who do not exercise) significantly influences energy level. You obtain different participants and put 30 in the "exercise" group and another 30 in the "non-exercise" group. Those in the "exercise" group exercised one hour per day for 2 weeks. Those in the "non-exercise" group refrained from exercising. (In SPSS, code exercise as 1 and non-exercise as 2). After the two weeks you obtained their energy level via a quantitative scale. You hypothesize that exercise status will significantly influence energy level. Use the following data to answer the following questions:

1. Is the study significant?

2. Is p <.05 or p>.05?

3. Do you reject or retain the null hypothesis?

4. What can you conclude about the hypothesis for this study?

5. What is the statistical sentence?

Definition Definition Probability of occurrence of a continuous random variable within a specified range. When the value of a random variable, Y, is evaluated at a point Y=y, then the probability distribution function gives the probability that Y will take a value less than or equal to y. The probability distribution function formula for random Variable Y following the normal distribution is: F(y) = P (Y ≤ y) The value of probability distribution function for random variable lies between 0 and 1.
