# Hypothesis Testing for Environmental Estimates

An environmentalist estimates that the more waste recycled by adults in the country is more than 1 pound per person per day. You want to test this claim. You find that the mean waste recycled per person per day for a random sample of 9 adults in the country is 2 pounds and the standard deviation is 0.3 pound. At a = 0.10, can you support the claim? assume the population is normally distributed.

a) Find the critical values and identify the rejection regions

To = (round to three decimal places)

b) Find the standardized test statistic

T = (round to three decimal places

c) Decide whether to (reject or fail) the null hypothesis?
