1. A survey was conducted asking how many times a month they eat at restaurants. The following results

were obtained:

1a) calculate the mean

1b) calculate the median

1c) calculate the mode

1d) calculate the third quartile

2. Given the following sample: 32, 76, 44, 58, 32, 19, 63, 51

2a) compute the range

2b) compute the interquartile range

2c) compute the variance

2d) compute the standard deviation

3. Given the following values: 3, 6, 7, 9, 10

3a) calculate the mean

3b) calculate the standard deviation

3c) calculate the z-score for each value

4. I did a study and found that my sample variable has a mean of 100 and a standard deviation of 10. Use

Chebyshev's Theorem to determine the percent of data in each range:

4a) 80-120

4b) 75-125

4c) 50-150

I further analyzed by dataset and the variable and discovered that it is normally distributed.

4d) What percent of my values would be between 85-115 in a normal distribution
