Answer:

Independent

Step-by-step explanation:

Dependent Sampling:

Dependent sampling is one in which the individuals in one sample are used to determine the individuals in the other sample.

But the third dash graders are divided into two groups independent of each other.

So the sampling is independent.

It is qualitative because it is showing quality irrespective of the number of students .

Quantitative Sampling is one in which the results change with the number of the individuals / tests etc. But in this experiment the number of the students is fixed so it is showing quality rather than quantity.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The null hypothesis is  H_o :  \beta_1 = 0

 The alternative hypothesis is  H_1 :  \beta_1 \ne 1

Step-by-step explanation:

From the question we are told that

        The number observations is  n =  100

         The  annual salary (in dollars) is  y

          The  mean score on teaching evaluation is  x

          The the relationship between the y and  x is

                y =  \beta_0  +  \beta _1 x + \epsilon

Where  \beta _1 is the mean of the equation so

  The null hypothesis is  H_o :  \beta_1 = 0

   The alternative hypothesis is  H_1 :  \beta_1 \ne 1
