a) which outcome was the most frequent outcome of the experiment =7
b) outcome was the least frequent =2
c)number of times we observe a 6 =15
d)% of times =(15/100)*100 =15%
e)Bell shaped
The chi-square distribution is _____________. Select one: a. Positively skewed b. Negatively skewed c. Normally distributed d. Uniformly distributed
The original population is severely left-skewed. The sampling distribution of sample mean is A. right-skewed for a sample size of 20 B. left-skewed for a sample size of 20. C. skewed for a sample size of 10 D. approximately normal for a sample size of 100

1.38 Sketch a skewed distribution. Sketch a histogram for a distribution that is skewed to the left. Suppose that you and your friends emptied your pockets of coins and recorded the year marked on each coin. The distribution of dates would be skewed to the left. Explain why.

In a positively skewed distribution with a mean (average) of 100 and median of 90 is A Positively skewed B. Negatively skewed C. Neither D. Cannot be determined by the information
The density curve is best describe as negatively skewed positively skewed abnormal approximately normal
When a distribution is skewed to the right, this means there is a a. Positive skew b. Negative skew c. No skew d. Multi-skewed
is this right-skewed, left-skewed, symmetric or uniform?

2. Sketch three histograms. One each that demonstrates a skewed-left distribution, a skewed-right distribution, and a bell-shaped distribution. For each one, state the relationship between the mean, median, and mode. Explain your reasoning
