Consider a normal distribution with mean 27 and standard deviation seven. what is the probability of value selected at random from this distribution is greater than 27?

answer:

50 per cent is the correct answer

2 x t divided by n

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
