How do you interpret a KSL or Kolmogorov-Smirnov-Lilliefors test?

If the test result is significant (Lower than or equal to 0.05) = The data is not normally distributed...

If the test result is not significant (Higher than 0.05) = The data is normally distributed...

This synchronize with the Statistical Hypothesis Assumption (Ho and Ha)

Ho means "Nothing Happen" and Ha means "Something Happen" then for

KSL and Shapiro Wilk test of normality assumption also.... If the test result reject Ha and accept Ho means "NOTHING HAPPEN" to data or the data is normally distributed

but if the result reject Ho and accept Ha means "SOMETHING HAPPEN" to data or in this case the data is NOT normally distributed.

What is the mortality rate of canavan disease?

Canavan's disease is a degenerative genetic disease of the brain. Approx 42,000 people in America are carriers and both parents must be carriers to pass it down. in cases where both parents are carriers the child has a 1 in 4 chance of developing the disease.

Of those children who do develop Canavan's most die before the age of 4, although there are some rare occurrences of children living to teens.

There is no cure and it is progressive so it is 100% fatal at some point.

What is the Median of 8 5 9 2 2?

The median is 5, because two values (2 and 2) are less than 5, and an equal number of values (8 and 9) are greater than 5. Generally speaking, the median is more informative than the average (mean), although a proper calculation of a "typical value" of a list of values depends on what the typical value will be used for.

How does the mean relate to the mode?

There is no direct relationship between the mean and mode.

What does it mean for a negative to be decreased by a negative?

It becomes less negative

To explain. Lets take a negative, eg -5.

If we decrease it by 1, it becomes -6 (where 1 is positive)

Thus if we decrease it by -1, it becomes -4 (as the -1 is negative)

Note that the final number could be positive,

For example, if you decrease -5 by -6, you get +1
