Answer: 4x - 13
<h2>
Step-by-step explanation:
</h2>
<em>First, we need to get triple of x:</em>
Triple of x is: 3x
<em>Next is to get the difference between 3x and 13:</em>
x + 3x -13
4x - 13
Hence, the variable expression is 4x - 13
Answer:
Step-by-step explanation:
a) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.8 and P(A)=0.2
Hence A and B are not independent.
b) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.6 and P(A)=0.3
Hence A and B are not independent.
c) If events A and B are independent we have
P(A/B) =P(A)
Jere P(A/B) = 0.5 and P(A)=0.5
Hence A and B are independent.
Answer:
We reject the null hypothesis.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 71
Alpha, α = 0.08
Population variance is known.
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
a) We calculate the z-critical with the help of z-table.
b)
Since,
We fail to accept the null hypothesis and reject the null hypothesis and accept the alternate hypothesis.
