Imagine that you randomly select a sample of 30 newborn infants and find that their mean weight is 8.1 pounds. the population mean of newborn infants is known to be 7.4 pounds with a standard deviation of 1.1 pounds. would a sample mean as large as 8.1 be more or less likely if n = 10? why?

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
