The area of this figure is 30 square cm.
Explanation
The figure consists of a rectangle and right angled triangle.
length of the rectangle l=6cm
breadth of the rectangle b=4 cm
area of the rectangle=lb=6*4 =
hypotenuse of the right angled triangle=5 cm
height h=4 cm
we have to calculate the base using pythagoras theorem

area of the triangle=
are of the figure=area of the rectangle+area of the triangle=24+6=30 sq cm
Answer:
a) reject H0
Step-by-step explanation:
The null and alternative hypotheses:
H0: the relative risk for moderate beer drinkers as compared to nondrinkers = 1
Ha: the relative risk for moderate beer drinkers as compared to nondrinkers ≠ 1
The level of significance, α = 0.1
Since the confidence interval for the relative risk of hypertension in moderate beer drinkers as compared to nondrinkers (0.47 to 0.90) does not contain the relative risk of 1, the null hypothesis will be rejected at the specified level of significance, 0.1. Therefore, the conclusion is to reject H0.
