1). In order to track the percentages of misdiagnoses by emergency room doctors, a sample of 900 patients revealed that 36 patients were misdiagnosed with indigestion instead of a heart attack. Historically, it was believed that physicians misdiagnose 6% of heart attacks.

Using an =0.05 level of significance, Complete the following steps to determine if this study proves that the misdiagnosis rate is less than the historical 6%?(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)

q =_____(two decimals)

x =_____

n =_____

p=_____(four decimals)

=_____

Set up the hypothesis statements (no spaces between characters):

H0:__________

H1:__________

Based on the hypothesis statements, will you use or (1 - ) to solve for zcrit?__________

What area will you use on the z-score table to find zcrit?__________

What is the value of zcrit?_________

Use the appropriate formula to solve for ztest:__________

Is the value of ztestfurther from zero than the value of zcrit?__________

Will yourejectorfail to rejectthe null hypothesis?__________

Does the study provide evidence that the misdiagnosis rate is less than the historical 6%?__________
