Question 3 assume that serum potassium levels in a healthy population are normally distributed, with a mean of 4.5meq/l and a standard deviation of 0.6meq/l. a. (2pts) what proportion of the population has serum potassium levels between 4.2 and 4.8meq/l?

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
