Since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.
Here:
we can use 1 sample proportion test to check the claim of John
H₀ : p₀ = 0.4
H₁ : p₀ ≠ 0.4
Test statistic is
z = p - p₀/√p₀(1-p₀)n
Let X be the random variable denoting the number of heads.
Now p = X/n
= 8/50
= 0.16
p₀ = 0.4
1-p₀ = 1-0.4
= 0.6
z = -3.464
since it is observed that I z I = 3.464 > 1.96 it is concluded that the null hypothesis is rejected.
Therefore we reject John's claim.

Answer:
The correct answer is s³/6
Step-by-step explanation:
<u>Points to remember</u>
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
It is given that, a pyramid has a square base with sides of length s the height of The pyramid is equal to 1/2 Of the length of a side on the base
<u>To find the formula:-</u>
Here side length a = s and
height h = 1/2(s) = s/2
Volume = (a²h)/3
= (s² * s/2)/3
= s³/6
The correct answer is s³/6
Answer:
1/36.
Step-by-step explanation:
A total number of possible outcomes = 36.
To get a sum of 12 the possible outcomes are just 6,6.
Answer:
The volume would be 470
Step-by-step explanation:
First do the first half of the shape 8 times 4 times 10 and get 320
Second do the second half of the shape 3 times 5 times 10 and get 150
150 plus 320= 470
