Answer:

D) The y interval shows exponential increase rather than linear increase.

Step-by-step explanation:

The y axis is the number of days, while the x axis is time spent outside.

If we take a look at the x- axis's data, we see that each different data set has an interval of 30. From this, we know that A and B are false.

If we take a look at the y axis, we can see that the number of days jumps from 1 to 2 to 4 to 8 to 16. This, graphed point by point shows an exponential line. We need a line that grows at the same rate to not show skewed data. Due to the fact that the graph would be exponential, our answer ends up being D.

The correct answer is that the y -axiz shows exponential increase, not a linear increase. Instead of counting consecutively by ones or twos, the y -axis goes from 1 to 2 to 4 to 8 (multiplying by 2). This will result in data that looks closer together than it actually is, and therefore is misleading.

Answer:

We need a sample size of least 119

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

Sample size needed

At least n, in which n is found when M = 0.09

We don't know the proportion, so we use \pi = 0.5, which is when we would need the largest sample size.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.09 = 1.96\sqrt{\frac{0.5*0.5}{n}}

0.09\sqrt{n} = 1.96*0.5

\sqrt{n} = \frac{1.96*0.5}{0.09}

(\sqrt{n})^{2} = (\frac{1.96*0.5}{0.09})^{2}

n = 118.6

Rounding up

We need a sample size of least 119
