Storing milk at temperatures colder than 35°F can affect its quality of taste. However, storing milk at temperatures warmer than

puteri [66]

t > 35 and t <40

So, Option A is correct.

Step-by-step explanation:

This is the question of compound inequality

Since the temperature of milk should be greater than 35 and the temperature should be less than 40 for keeping the quality of milk.

So, Representing it in inequality the union of both conditions we get:

t > 35 and t <40

So, Option A is correct.

It is known that the length of time that people wait for a city bus to arrive is right skewed with mean 6 minutes and standard d

Natali [406]

Answer:

The standard deviation of the sampling distribution of the sample wait times is of 0.8 minutes.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30. Otherwise, the mean and the standard deviations holds, but the distribution will not be approximately normal.

Standard deviation 4 minutes.

This means that $\sigma = 4$
