The University of Colorado conducted a Halloween candy consumption study. The researchers measured the amount of candy 38 trick-or-treaters aged 6 to 11 years collected on Halloween night and their subsequent weight gain two days later. The two-day weight gain (in pounds) after Halloween for the trick-or-treaters in this sample is given below. 2.0, 2.1, 3.0, 2.6, 2.7, 2.4, 3.2, 2.8, 1.6, 2.9, 2.3, 2.0, 2.9, 2.7, 3.5, 2.0, 3.1, 3.5, 2.6, 2.2, 1.9, 2.8, 2.8, 3.0, 3.2, 2.4, 3.4, 2.7, 2.8, 1.9, 3.3, 2.2, 2.5, 2.9, 1.8, 2.4, 2.8, 2.9 Use this sample data and a 95% level of confidence to estimate the mean two-day weight gain after Halloween of trick-or-treaters aged 6 to 11 years.
