A hospital president claims that the average salary of registered nurses at her hospital is more than $57,000. You test this claim by surveying 37 registered nurses at this hospital and find they have a mean salary of $57,425. Assume the population standard deviation is $1,750. At the 0.10 level of significance, is there enough evidence to SUPPORT the claim of the hospital president? 1.) If it's a test for mean, do we know the population standard deviation? Based on your answer in #1, which calculator will you use: A.) Mean - σ Known, B.) Mean - σ Unknown or C.) Proportions *Two different problems trying to figure out which one is known and unknown*
