If the prediction is wrong, by how much do you expect it to be wrong?Last year, 58% of butterflies in NC were monarchs. We hypothesize that the proportion changed this year (Hint: I said "changed", not greater or less than! Also, the word proportion is a hint on which test to use in your calculator). We do a study of 250 butterflies and 170 were monarchs. Use an alpha = 0.05 Find the p-value. Write it in standard form or as an exponent.
