Suppose a botanist grows many individually potted eggplants, all treated identically and arranged in groups of four pots on the greenhouse bench. after 30 days of growth, she measures the total leaf area x of each plant. assume that the population distribution of x is approximately normal with mean = 800 and sd = 90. which of the following is a true statement about the sampling distribution for the average of each group of four plants? mean = 800 and sd = 90 mean = 800 and sd = 90/4 mean = 800 and sd = 90/2 mean = 800/4 and sd = 90/4

there is no question content here, but you for the free points! : d

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

the answer is c 150
