You are conducting a study to see if the proportion of men over the age of 50 who regularly have their prostate examinedis significantlyless than0.31. A randomsample of 775 men over the age of 50 found that 200 have their prostate regularly examined.Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 10% 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.) H0: Select an answer x p s s p ? > = < H1: Select an answer p s s p x ? < > =

Based on the hypotheses, find the following:

Test Statistic = Critical-value=

Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions.The arrows can only be dragged toz-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).

The correct decision is to Select an answer: Accept the alternative hypotheis, Fail to reject the null hypothesis, Accept the null hypothesis, Reject the null hypothesis .

The correct summary would be: Select an answer: There is not enough evidence to support the claim, There is not enough evidence to reject the claim, There is enough evidence to support the claim, There is enough evidence to reject the claim that the proportion of men over the age of 50 who regularly have their prostate examinedis significantly less than0.31.
