Answer 1

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Most vertebrate adult body sizes remain constant or increase throughout their lives. Marine iguanas are different in that they can actually decrease in size, in periods of low food availability. Examine the data set here, and test the hypothesis that on average across time, iguana length changed (increased) by 1 mm. Paste your R code in the answer box, and tell me your conclusion.
