What is a Dependent event

1 answer:

nignag [31]4 years ago

Step-by-step explanation: If events are dependent, this means that the outcome of the first event will affect the outcome of the second event.

Let's look at an example.

Gianna has 8 blue socks and 4 red socks in her sock drawer. She chooses one sock at random and puts its on. She then chooses another sock without looking. Find the probability of the following event.

P (red, then red)

These would be dependent events because if she puts a sock on and doesn't replace it, there is 1 fewer sock in the drawer which affects the probability.

Solve the equation 2p/3-12=-2

-BARSIC- [3]

Hey there!

$\frac{2p}{3} - 12 = -2$

Firstly, we are going add $12$ on each of the sides that we're working with. like ↓

$p - 12 + 12 \\ \\ = -2 + 12$

This gives us $\frac{2}{3}p = 10$ (if you are wondering how we got the out come of $10$ it is because I added $-2 + 12 = 10$

Now multiply $\frac{3}{2}$ on each of your sides

$\frac{3}{2} ( \frac{2}{3}p) \\ \\ = \frac{3}{2} (10)$

Cancel the first set and you will find the value of $p$

$p = 15$

Good luck on your assignment and enjoy your day

In a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cl

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Given that in a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less.

The sample size n = 80

no of wells less than 100 feet deep=27

Sample proportion = $\frac{27}{80} =0.3375$

a) Create hypotheses as

$H_0: p = 0.30\\H_a: p >0.30\\$

(Right tailed test)

p difference $= 0.3375-0.30 = 0.0375$

Std error of p = $\sqrt{\frac{0.3(0.7)}{80} } =0.0512$

b) Assumptions: Each trial is independent and np and nq >5

c) Z test can be used.

Z= p diff/std error = $\frac{0.0375}{0.0512} =0.73$

p value = 0.233

d) p value is the probability for which null hypothesis is false.

e) Conclusion: Since p >0.05 we accept null hypothesis

there is no statistical evidence which support the claim that more than 30% are drilled.
