true
Yes, and is equal to 1. This is true for normal distribution using any mean and variance.
In a normal distribution, the mean, median, and mode are all equal. Therefore, if the mean is 40, the median is also 40. This property holds true for any normal distribution regardless of its specific values.
true
It is symmetrical

Yes- this can be proved from the normal distribution function.
yes it is true
true
Yes, it is true; and the 2 quantities that describe a normal distribution are mean and standard deviation.
Yes, and is equal to 1. This is true for normal distribution using any mean and variance.
True * * * * * No. The Student's t-distribution, for example, is also bell shaped.
No. The Normal distribution is symmetric: skewness = 0.
true
yup, it's a bell curve
The standard normal distribution is a normal distribution with mean 0 and variance 1.
