Mean birthweight is studied because low birthweight is an indicator of infant mortality. A study of babies in Norway published i

n the International Journal of Epidemiology shows that birthweight of full-term babies (37 weeks or more of gestation) are very close to normally distributed with a mean of 3600 g and a standard deviation of 600 g. Suppose that Melanie is a researcher who wishes to estimate the mean birthweight of full-term babies in her hospital. What is the minimum number of babies should she sample if she wishes to be at least 95% confident that the mean birthweight of the sample is within 100 grams of the the mean birthweight of all babies? Assume that the distribution of birthweights at her hospital is normal with a standard deviation of 600 g.

sashaice [31]

Answer:

1.1

Step-by-step explanation:

Find the mean of the data:(3+4+5+5+5+6+6+6+7+8)/10 = 5.5Step 2: Find the difference between each data and mean:Difference between 3 and 5.5 is 2.5Difference between 4 and 5.5 is 1.5Difference between 5 and 5.5 is 0.5Difference between 5 and 5.5 is 0.5Difference between 5 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 7 and 5.5 is 1.5Difference between 8 and 5.5 is 2.5Step 3: Add all the differences:2.5+1.5+0.5+0.5+0.5+0.5+0.5+0.5+1.5+2.5 = 11Step 4: Divide it by the number of data:11/10 = 1.1So, the MAD = 1.1

If f(x) = x^2-2x-24 and g(x) = x^2-x-30, find (f-g)(x).
yaroslaw [1]

Answer:

-x+6

Step-by-step explanation:

if f(x) = x^2-2x-24 and g(x) = x^2-x-30, find (f-g)(x).

Do to this, you have to subtract equation g from equation f.

If you write it down and subtract them, your x^2 will cancel out and you will be left with -2x - (-x) and -24 - (-30). This will leave you with -x +6
