Would it be (-3)^7? (-2187)
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.

Step-by-step explanation:
Answer:
Uneffected.
Step-by-step explanation:
The order of the numbers doesn't affect the product in multiplication problems.
For example, we need to multiply 2 × 10.
We can write it as : 2×5×2
2×(5×2) = 2×10 = 20
Also,
(2×5)×2 = 10×2 = 20
Hence, it will remain unaffected when we multiply numbers.
