Answer:

Choice C

Step-by-step explanation:

A and B represent symmetric distributions, that is most data values lie in the middle and the both tails are equally longer.

C represents a positively skewed distribution, most of the data values lie to the left with a few points skewing the shape of the distribution to the right.

Answer:

Option C is the answer.

Step-by-step explanation:

We will try to understand the behavior of each graph given in options.

A). In this graph bars show the symmetry on both the sides of the highest bar. Therefore, the graph represents a symmetric graph.

B). In this graph most of the points have been plotted on the left side of the maximum data value and has a long tale on the left side. Therefore the graph is negatively skewed graph.

C). In this graph most of the points have been plotted on the right side of the maximum valued data. Hence it has a tale on the right side. Therefore, The given graph is positively skewed.

D). This graph has the equal tails on each side of the maximum value. Therefore represents a symmetric graph.

Option C is the correct option.

Write the null and alternative hypotheses in words and then symbols for each of the following situations.
Marrrta [24]

Answer:

A) the hypothesis in words and symbols are;

Null hypothesis: Grades have not improved for most students

Alternative hypothesis: Grades have improved for most students

Null hypothesis; H0: p^ = 0.5

Alternative hypothesis; Ha: p^ > 0.5

B) Null hypothesis: During march madness, employees averaged 15 minutes per day on non - business activities

Alternative hypothesis: During march madness, employees averaged more than 15 minutes per day on non-business activities

Null hypothesis; H0: μ = 15

Alternative hypothesis; Ha: μ > 15

Step-by-step explanation:

A) We are told that they sampled 200 of the students who used their service in the past year and ask them if their grades have improved or declined from the previous year. Thus, there will be a 50% chance of success for their grades to have improved and a 50% chance for it to remain the same.

Thus; p^ = 0.5

So the hypothesis in words and symbols are;

Null hypothesis: Grades have not improved for most students

Alternative hypothesis: Grades have improved for most students

Null hypothesis; H0: p = 0.5

Alternative hypothesis; Ha: p > 0.5

B) We are told that they estimate that on a regular business day employees spend on average 15 minutes of company time checking personal email, making personal phone calls, etc

Also, They also collect data on how much company time employees spend on such non-business activities during March Madness.

The hypotheses in words and symbols are;

Null hypothesis: During march madness, employees averaged 15 minutes per day on non - business activities

Alternative hypothesis: During march madness, employees averaged more than 15 minutes per day on non-business activities

Null hypothesis; H0: μ = 15

Alternative hypothesis; Ha: μ > 15
