1. Create a plot of a frequency distribution (also known as a histogram) of the number of eggs laid in past breeding seasons. This plot should follow the formatting guidelines listed below. To determine whether the astelars laid fewer eggs in the current breeding season than expected, we must estimate the probability of observing fewer than 2217 eggs in a past breeding season. Before we can estimate that probability, we first need to determine whether a normal probability distribution reasonably describes the frequency distribution of data for past breeding seasons. If not, we should calculate probabilities from a frequency distribution of the data instead of from a normal probability distribution.  (N = 37 breeding seasons) Bin values: 2000-2200, 2200-2400, 2400-2600, 2600-2800, 2800-3000 Formatting Instructions Chart type: Histogram Quick layout: Layout 1 Y-axes title: “Frequency”; Font size = 18 Y-axis numbers: Font size = 14 X-axis title: “Number of eggs”; Font size 18 X-axis numbers: Font size = 14
