Use StatKey or other technology to create the randomization distribution for the situation in Exercise B.48. Use the distribution to calculate a p-value. Using α = 0.05, state the conclusion in context.

Exercise B.48

The dataset FloridaLakes is introduced in Data 2.4 on page 68, and we return to the dataset in Exercise B.45 on page 315. To see if there is evidence of a negative correlation between pH in lakes and mercury levels in fish, the hypotheses are H₀: ρ = 0 vs H_a: ρ < 0. For the observed sample, with n = 53, we have r = −0.575.
