The fear of negative evaluation (FNE) scores for 11 female students known to suffer from the eating disorder bulimia and 14 female students with normal eating habits are presented below. In this question, we will compute a 95% confidence interval for µ1 −µ2, the difference of the population mean FNE scores for bulemic and normal female students respectively. Bulimic Normal 21 21 13 18 13 24 6 11 10 13 16 19 20 14 13 7 25 8 10 19 19 15 16 23 20 (a) Treating the bulimic and normal groups as populations one and two respectively, calculate ¯y1, s1, y¯2 and s2. You can just write out these values. You do not need to copy and paste the code. (b) Calculate sp and the standard error of ¯y1 − y¯2. (c) Provide the appropriate t-curve critical value for constructing a 95% confidence interval for µ1 − µ2. (d) Provide a 95% confidence interval for µ1 − µ2.

step-by-step explanation:

not sure about this one man

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.

his wife got 46,000

his son gets 11,500

each charity gets 6,900

hope this

the cross section of an object is the shape you get when you cut straight through an object.

thus the cross section of the human hair is a circle. hence the cross sectional area is the area of a circle and area of circle is :

a = 3.14 × r²

we are given that the average width of human hair is = 4 × (1 / 10³) cm.

so the diameter of the circle is = 4 × (1 / 10³) cm.

∴ radius r = (diameter/2) = 2 × (1/10³) cm

now area a = 3.14 × (2 × (1/10³))² cm²

scientific notation is a standard way of writing very large and very small numbers so that they’re easier to both compare and use in computations. to write in scientific notation, follow the form

n × 10 ᵃ

where n is a number between 1 and 10, but not 10 itself, and a is an integer (positive or negative number).

so area can be rewritten in scientific notation as :

⇒ 3.14 × 4 × (1/10⁶)

⇒ 12.56 × 10 ⁻⁶ cm²

⇒1.256 × 10⁻⁷ cm²
