As the sample size increases, the O population mean increases O standard error of the mean increases O standard deviation of the population decreases O standard error of the mean decreases

A sample of size n is selected at random from an infinite population. As n increases, which of the following statements is true? O The population standard deviation increases. O The population standard deviation decreases. O The standard error of the sample mean increases.

Which of the following is true in a normal distribution?

The mean can't be less than zero.

Median and mean divide the distribution into two equal parts.

The area under the curve is 0.68.

Mode and the 3rd quartile are equal.

There are 90 people in the restaurant. The probability al sameone ordering a drink with the food is 45%. Use Normalapproximation of Binomial Distribution, Pick the correct answers.

Probability that more than 36 but less than or equal to 43 will order a drink is about 51%.

The standard deviation of the Binomial distribution is 4.7196

Probability that more than 36 but less than or equal to 43 will order a drink is about 57%.

You want the probability that at least 37 will order a drink, The z-score will be 0.8475

You want the probability that exactly 45 will order a drink. The z-score will be 0.9540

The standard error for sample proportion is 0.00275

The Probability of exactly 45 is 0 because Normal distribution is a continuous distribution.

You want the probability that no more than 37 will order a drink. The z-score will be -0.635

Probability that more than 36 but less than or equal to 43 will order a drink is about 54%.
