Normal distribution

Question 1

M =mean

q(bom sign) = standard deviation

Answer 1

Mean is the centre of the bell curve.

standard deviation= the spread or divergence of data

Question 2

Probability as pertains to standard deviation.

Answer 2

P( x>50)= to the probability in brackets out of the total:

Probabilities of between two numbers.

Probability : out of 1
Distribution of regions of space(Bell curve): 100

Question 3

What does Normal distribution indicate.

Answer 3

Determine if a data set is well-modeled by a normal distribution _ a probability of distribution.

identified using dependent variables or constants_ time, hight, width, years, age.

Question 4

Calculataion for normal distribution

Answer 4

Stat -> Dist -> Norm -> Ncd

Lower bd: prescribed number
Upper bd: highest number(999999)
m= mean
q(bom)= standard deviation
