An environmental group conducted a study to determine whether crows in a certain region were ingesting food containing unhealthy levels of lead. A biologist classify lead levels in the population greater than a mean of 6.0 (ppm) as and healthy. The lead levels of a random sample of 23 crows in the region were measured and recorded. That test from this sample showed lead level in these crows at a mean of 6.073 and the sample standard deviation at .434 with a 10% significance Level, is there convincing statistical evidence that, on average, the crows in this region are in testing and healthy levels of lead? Assume that the conditions necessary for a hypothesis test have been met.

a. Defined the perimeter of the entrance and stay the Null and alternative hypothesis

B. Fill in the formula find the test statistic find the P value

t= x-uo/s/Square root of n

c. Compare the P value and the alpha and write a conclusion for this hypothesis test
