Area of rectangle = l × b
l = 70cm
b = 8cm
Area = 70 × 8 = 560cm²
Area of rectangle = l × b
l = 78cm
b = 15cm
Area = 78 × 75 = 1170cm²
1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5
2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4
probability both balls are blue : 3/5 * 1/4 = 3/20 <==

Not much more to say about this. Just multiply the integer by the coefficient.
Answer: The value of test statistic is 0.696.
Step-by-step explanation:
Since we have given that

Similarly,

At 0.01 level of significance.
Hypothesis are :

So, the test statistic value would be

Hence, the value of test statistic is 0.696.
