Transcribed Image Text:You are conducting a study to see if the proportion of men over the age of 50 who regularly have their
prostate examined is significantly less than 0.32. A random sample of 760 men over the age of 50 found
that 202 have their prostate regularly examined. Do the sample data provide convincing evidence to
support the claim? Test the relevant hypotheses using a 1% level of significance. Give answer to at least 4
decimal places.
What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.)
Ho: P
H₁: p
Based on the hypotheses, find the following:

Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions. The
arrows can only be dragged to z-scores that are accurate to 1 place after the decimal point (these values
correspond to the tick marks on the horizontal axis). Select from the drop down menu to shade to the left,
to the right, between or left and right of the z-score(s).
