By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (6.7), m is the mean (5), sd is the standard deviation (7.1) and n is the sample size (29).
Replacing we have:
z (6.7) = (6.7 - 5) / [7.1 / sqrt (29)]
z = 1.289
If we look in the normal distribution table (attached), we have that the probability is 0.8997, therefore:
1 - 0.8897 = 0.1003
So the conditional probability of a herd sample earning at least 6.7 pounds per steer is 10.03%.
Now the hypothesis tells me:
m> 5
The probability is somewhat low, therefore, the most correct thing is to reject the hypothesis even though it is a fact that can occur.
There are 7 parent tigers
Parents = 7
7 tigers each have 7 children. That means there's total of 7 × 7 children.
Children = 7 × 7 = 49
Each child has 7 friends. That means there's total of 49 × 7 friends.
Friends = 49 × 7 = 343
Total = 7 + 49 +343 = 399 TIGERS
I'm not a tiger so I'm not counting myself.
The new statement will be:
- The nuclear power plants wastes are very toxic.
- Air pollution from Nuclear power plants is much lower that from power
- plants that make use of fossil fuels.
- Power plants that are Nuclear are regarded as safe.
- The risks of nuclear power is much more lower than the benefits.
<h3>What changed my mind in the above?</h3>
Nuclear energy is known to be one that produce a lot of radioactive waste and this tends to pose a threat to human health and the environment.
Hence, The new statement will be:
- The nuclear power plants wastes are very toxic.
- Air pollution from Nuclear power plants is much lower that from power
- plants that make use of fossil fuels.
- Power plants that are Nuclear are regarded as safe.
- The risks of nuclear power is much more lower than the benefits.
