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 0.4. A random sample of 700 men over the age of 50 found that 196 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.) H0: P (choose the correct symbol: <,>, equal to, =, greater than or equal to, or less than or equal to ) H1: P (choose the correct symbol: <,>, equal to, =, greater than or equal to, or less than or equal to ) 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 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). Is the sample Left of a value, Right of a value, between two values or 2 regions? The correct decision is to: choose one below Fail to reject the null hypothesis Accept the alternative hypothesis accept the null hypothesis reject the null hypothesis . The correct summary would be: __?__ that the proportion of men over the age of 50 who regularly have their prostate examined is significantly less than 0.4. Choose one below there is not enough evidence to reject the claim there is not enough evidence to support the claim there is enough evidence to reject the claim there is enough evident to support the claim

H1: P (choose the correct symbol: <,>, equal to, =, greater than or equal to, or less than or equal to )
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 to z-scores that are accurate to 1 place after the decimal point (these values correspond to the tick marks on the horizontal axis).

Is the sample Left of a value, Right of a value, between two values or 2 regions?
The correct decision is to: choose one below
Fail to reject the null hypothesis
Accept the alternative hypothesis
accept the null hypothesis
reject the null hypothesis .
The correct summary would be: __?__ that the proportion of men over the age of 50 who regularly have their prostate examined is significantly less than 0.4. Choose one below
