Many questions in research can be expressed as two competing statements about the population parameter. These two statements are

called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.
Suppose that 70% of all faculty members at large public universities in the US use iClickers in their classrooms. We would like to assess if the proportion of faculty members at UM who use iClickers in the classroom is less than the stated rate.

What are all of the x-intercepts of the continuous function in the table? (0, 8) (–4, 0) (–4, 0), (4, 0) (–4, 0), (0, 8), (4, an
crimeas [40]

Answer:

The  x-intercepts of the continuous function in the table are:

(-4,0) and (4,0).

Step-by-step explanation:

We are given a table of values of the continuous functions as:

(0, 8) (–4, 0) (–4, 0), (4, 0)

The x-intercept of a function is a point on the x-axis i.e. where y=0. (i.e. The x-intercept is where a line crosses the x-axis ).

Here y=f(x).

Hence from the given set of values we have:

f(x)=0 when x= -4 and x=4.

Since we are given the points as (-4,0) and (4,0).

Hence, the x-intercepts of the function f(x) is: (-4,0) and (4,0).

Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same rec
Kisachek [45]

Answer:

2.5h = 3g

Step-by-step explanation:

Given

Sugar = 2\frac{1}{2}\ cups

Bars = 3\ pans

Required

Determine the equation for h pans and g cups

We have that:

Sugar = g

Bars = h

To do this, we make use of the following equivalent ratios.

Bars : Sugar = Bars : Sugar

So, we have:

3 : 2\frac{1}{2} = h : g

Express fraction as decimal

3 : 2.5 = h : g

Express as fraction

\frac{3}{2.5} = \frac{h}{g}

Cross multiply

2.5h = 3g

No options were given. So, I will stop here
