a) Use the Central Limit Theorem to approximate the probability that you win in 10% or fewer of those 10 games. [Big Hint: Find the mean and standard deviation of the sampling distribution. Then use z-scores and the normal probability table or the normalcdf( command on your calculator to find the probability.]

Describe two methods for assessing whether or not a distribution is approximately Normal. What is a Normal probability plot? How do you interpret a Normal probability plot? When is it appropriate to use the NormalCDF and Inverse Normal functions on the calculator? Chapter 3: Describing Relationships. 3.1 Scatterplots and Correlation (pp.142-156) 1.

Find the probability that a simple random sample of 4. 9. people will result in a sample mean greater than 1. 05, P( ̅ x >105) . Checking Assumptions. In order to use the normal calculator in StatCrunch to calculate this probability, we first need verify that the sampling distribution is normally distributed. There are two conditions we need ...

PS.19The student will identify the meaning of sampling distribution with reference to random variable, sampling statistic, and parameter and explain the Central Limit Theorem. This will include sampling distribution of a sample proportion, a sample mean, a difference between two sample proportions, and a difference between two sample means.

A sample size of 30 is a “large sample” in some textbook discussions of “normal approximation”; yet 30,000 observations still may be too few to assess a rare, but serious teratogenic effect. ... Here is an online calculator that allows you to determine the sample size for a measurement continuous variable in a single sample study: http ...

Construct a normal probability plot to assess normality and a boxplot in order to check for outliers. For the firs data set, enter the data in L1 (press STAT, select Edit) of the calculator and open two plots, one with a modified box plot (the fourth icon) and another with the normal probability plot, which is the last icon type in the 2nd Y ...

The activity also introduces how percentiles are determined using a standard normal table or by using a calculator. The associated height project provides an opportunity to discuss appropriate sampling techniques, the formula for the sample standard deviation, and a context where a set of normally distributed data is analyzed through the lens ...

The power is a probability and it is defined to be the probability of rejecting the null hypothesis when the alternative hypothesis is true. After plugging in the required information, a researcher can get a function that describes the relationship between statistical power and sample size and the researcher can decide which power level they ...
