Answer:

  J  3/4 cup

Step-by-step explanation:

<u>Step 1</u>: read and understand the question.

  The question is giving you amounts of flour and 2 types of sugar.

  The question is asking for a difference between two quantities:

  • the amount of flour (2 1/4 cups)
  • the combined amount of sugar (3/4 cup white, 3/4 cup brown)

<u>Step 2</u>: determine the relations you need to use to solve the problem

   You need the <em>combined amount</em> of sugar, which you find by adding the quantities of each of the kinds.

  3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined

 You need the <em>difference</em> of that quantity from the quantity of flour, which you find by performing subtraction:

  flour - sugar = (2 1/4) - (6/4) . . . . cups

<u>Step 3</u>: Use your knowledge of arithmetic.

  (2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4

<u>Step 4</u>: Answer the question that was asked.

  The difference between the flour and sugar amounts is 3/4 cup.

In 1980 and again in 2010, a Gallup poll asked a random sample of 1000 US citizens people "Are you in favor of the death penalty
Digiron [165]

Answer:

H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)

0.02

Step-by-step explanation:

Given that:

Sample size in both 1980 and 2010 = 1000 samples :

Proportion in favor :

P(1980) = 0.66

P(2010) = 0.64

To test the hypothesis :

Null hypothesis :

Proportion in favor are the same in both years

Null hypothesis = H0 = p(1980) = p(2010)

Alternative hypothesis :

Proportion in favor in 1980 is greater than that in 2010

Alternative hypothesis = H1 : P(1980) > P(2010)

The sample statistic :

P(1980) - p(2010)

0.66 - 0.64

= 0.02
