Question 1 0.5 pts Find a news article that communicates a proportion. Note that it might be expressed as a percentage, since it is often easier for people to put percentages in perspective. If the article has more than one proportion, choose only one proportion to use for this activity. Remember that a proportion is calculated from binary categorical data, so not all percentages represent proportions (for example, "spending has increased by 2% in the past year\" measures the change for a quantitative variable, so this wouldn't work for this activity). In the text box below, include a web link to the news article. Quote (copy and paste) one sentence from that article that gives the proportion and puts it in context.

Answer using the number of decimal places that are communicated in the article. If the proportion was expressed as a percentage, divide by 100 to express it as a proportion (a value between 0 and 1). For example, if the article reported that "53% of children in the US own a smartphone by age 11", then 33 would be equal to 0.53. If the percentage had been reported as 53.2%, then 33 would be equal to 0.532. i Question 3 0.5 pts What critical value should you use for a 99% condence interval? Answer to three decimal places. ? Question 4 1 pts Calculate the standard error for a 99% condence interval assuming a sample size of 200. Answer to four decimal places. Remember that standard error is calculated as SE(13) = x/qA, where q : 1 p. We will be assuming a sample size of 200 for this activity since not all news articles will report the sample size that was used. Using the unrounded values for the standard error and the critical value, calculate the lower limit of the 99% condence interval assuming a sample size of 200. Answer as a proportion (between 0 and 1) to four decimal places. Using the unrounded values for standard error and the critical value, calculate the upper limit of the 99% condence interval assuming a sample size of 200. Answer as a proportion (between 0 and 1) to four decimal places. Write one sentence to interpret the 99% condence interval. You can express the limits of the condence intervals as percentages if you prefer to do so for the interpretation. Be specic about what the condence interval is estimating.
