You would like to determine if there is a higher incidence of smoking among women than among men in a neighborhood. Let men and

women be represented by populations 1 and 2, respectively. The relevant hypotheses are constructed as....a) h0: p1-p2 ≥ 0 h1: p1-p2 < 0b) h0: p1-p2≤ 0 h1: p1-p2 > 0

Answer:

For this case we want to test if there is a higher incidence of smoking among women than among men in a neighborhood (alternative hypothesis). And we define p1 for men and p2 for women, so for this case the best system of hypothesis are:

Null hypothesis:p_1- p_2 \geq 0

Alternative hypothesis: p_1 -p_2

And the best option would be:

a) h0: p1-p2 ≥ 0 h1: p1-p2 < 0

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".  

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".  

Solution to the problem

For this case we want to test if there is a higher incidence of smoking among women than among men in a neighborhood (alternative hypothesis). And we define p1 for men and p2 for women, so for this case the best system of hypothesis are:

Null hypothesis:p_1- p_2 \geq 0

Alternative hypothesis: p_1 -p_2

And the best option would be:

a) h0: p1-p2 ≥ 0 h1: p1-p2 < 0

A rectangular table is 5 1/4 feet by 3 3/4 feet. What is the area of the table?
enot [183]

Answer:

19 11/16 or 315/16

Steps:

Turn the fractions into an improper fraction and then multiply straight across

5 1/4 = 21/4

3 3/4 = 15/4

(21/4)*(15/4)= 315/16= 19 11/16

Yes you got it right :)

Find the equation of the line given the slope and the y-intercept
GREYUIT [131]

Answer:

y = \frac{1}{2}x + 3

Step-by-step explanation:

The equation for a linear graph is usually written in the following format...

y = mx + b

Where m would be the slope, usually referring to rise over run and b would be the y-intercept (where the line crosses the y-axis). From the graph, we can see that the line crosses the y-axis at point 3 so b would be 3. The graph also shows us that for every 1 value that the line rises it moves to the right 2 values. Therefore, the slope would be 1/2. Using these values we can create the following equation...

y = \frac{1}{2}x + 3
