    A teacher hypothesized that in her class, grades of girls on a chemistry test were the same as grades of boys. If the probability value of her null hypothesis was 0.56, it suggested:
    a. We failed to reject the null hypothesis
    b. Boys' grades were higher than girls' grades
    c. Girls' grades were higher than boys' grades
    d. The null hypothesis was rejected

    a. We failed to reject the null hypothesis

    Due to a high probability.
