In 2011, when the Gallup organization polled investors, 34% rated gold the best long-term investment. However, in April of 2013 Gallup surveyed a random sample of U. S. adults. Respondents were asked to select the best long-term investment from a list of possibilities. Only 241 of the 1005 respondents chose gold as the best long-term investment. • With 95% confidence, compute the margin of error of the sample proportion. • Compute and describe a 95% confidence interval in the context of the case. • Do you think opinions about the value of gold as a long-term investment have really changed from the old 34% favorable rate, or do you think this is sample variability? Explain your answer using the calculated statistics. • Suppose the Gallup organization wants to offer a new investment option and wants to estimate, to within 5%, the proportion of customers who are likely to make this new investment with 95% confidence. How large a sample do they need?

•broussard skateboard’s sales are expected to increase by 15% from $8 million in 2016 to $9.2 million in 2017. its assets totaled $5 million at the end of 2016. broussard is already at full capacity, so its assets must grow at the same rate as projected sales. at the end of 2016, current liabilities were $1.4 million, consisting of $450,000 of accounts payable, $500,000 of notes payable, and $450,000 of accruals. the after-tax profit margin is forecasted to be 6%, and the forecasted payout ratio is 40%. use the afn equation to forecast broussard’s additional funds needed for the coming year
