Math question

    Problem 12 in Chapter 9 described a study that examined
    the spotlight effect, which refers to people overestimating
    the extent to which others notice their
    appearance or behavior. In the study, n = 9 participants
    were asked to put on a Barry Manilow T-shirt
    and walk into a room where other students were
    working. Later, the participants were asked to estimate
    how many students in the room noticed the shirt. The
    average estimate for the nine participants was M = 6.4
    with SS = 162.
    a. Make a point estimate of the number of people that
    participants think noticed the shirt.
    b. Compute the 90% confidence interval for the mean
    number of people.
    c. After interviewing the students in the room, the
    researchers found that an average of μ = 3.1 students
    actually noticed the shirt. Based on this value
    and your answers from a and b, how much do people
    overestimate t
