Question
![In order to track the percentages of misdiagnoses by emergency room doctors, a sample of 950
patients revealed that 45 patients were misdiagnosed with indigestion instead of a heart attack.
Historically, it was believed that physicians misdiagnose 7% of heart attacks.
Using an a=0.05 level of significance, Complete the following steps to determine if this study proves
that the misdiagnosis rate is less than the historical 7%?
(NOTE: All areas are reported to four decimal places; all z-scores are reported to two
decimal places except the two special cases listed at the bottom of the table.)
Insert the following values from the question:
p=
% =
(two decimals)
(two decimals)
n3=
(four decimals)
Set up the hypothesis statements (no spaces between characters):
Ho
H
Based on the hypothesis statements, will you use a or (1- a) to solve for zent?
What area will you use on the z-score table to find zert?
What is the value of z?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa88278f8-f7b1-4ae2-ba38-1fa5ea67debd%2Fb5ab71c3-ec10-46e4-b833-18f1958184b9%2F1w8e3q4_processed.jpeg&w=3840&q=75)
