Find the upper 20%of the weight?

meriva

Answer:

The upper 20% of the weighs are weights of at least X, which is $X = 0.84\sigma + \mu$ , in which $\sigma$ is the standard deviation of all weights and $\mu$ is the mean.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Upper 20% of weights:

The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then

$Z = \frac{X - \mu}{\sigma}$

$0.84 = \frac{X - \mu}{\sigma}$

$X = 0.84\sigma + \mu$

The upper 20% of the weighs are weights of at least X, which is $X = 0.84\sigma + \mu$ , in which $\sigma$ is the standard deviation of all weights and $\mu$ is the mean.

Consider the statement "If Oscar eats Chinese food, then he drinks milk." a. Write the converse of the statement. b. Write the c

m_a_m_a [10]

Step-by-step explanation:

Consider the provided statement.

"If Oscar eats Chinese food, then he drinks milk."

Here p is Oscar eats Chines food and q is he drinks milk.

Converse is interchange the two statement.

Converse: "If Oscar drinks milk, then he eats Chinese food"

Contrapositive is negative both statement and interchanges them.

Part (b) Contrapositive: "If Oscar doesn't drink milk, then he doesn't eat Chinese food"

Part ( c) If the provided statement is true, then the contrapositive is always true because contrapositive is logically equivalent to the provided statement. If provided statement is false, then the contrapositive is always false.

Part (d) let the original statement is true, and we know that Oscar drinks milk, then we still would not be able to make any conclusion about his Chinese food eating habits.

Because the statement is true if "Oscar eats Chinese food" is true Oscar may or may not eat chines food.

The above converse may be false.

Part (e) Suppose the original statement is true, and that Oscar does not drink milk. It means Oscar doesn't eat Chinese food. Because if Oscar eats Chinese food, then according to the truth of the original statement "Oscar drinks milk" to be true which is the contradiction.

Thus, Oscar doesn't eat Chinese food.
