The Distribution of Sample Means expresses the way in which sample means taken from a population and of a given sample size are
Bess [88]

Answer:

a. True

Step-by-step explanation:

This is because, since the sample mean equals the population means, the distribution of the sample means about the sample size would also be the distribution of the sample size distributed about the population mean.

This usually results in a normally distributed population for a sample size greater than 30.

So, if the sample size is greater than 30, the population mean and sample mean would have the same value and distribution.

zimovet [89]

Answer:

6 bananas, 24 bapples.

Step-by-step explanation:

If Omar has 4 times as many apples as bananas: then if a is the number of apples and b is the number of bananas, then:

Let's say there are b bananas

Therefore there must be 4b apples

In total that gives 5b fruit.

Therefore since there are 30 fruit in all:

5b = 30

Therefore, b = 6

And since there are 30 fruit overall, 30 - 6 = 24

So there 24 apples overall and 6 bananas.
