Hospital admissions for asthma in children younger than 15 years was studied1 in scotland both before and after comprehensive smoke-free legislation was passed in march 2006. monthly records were kept of the annualized percent change in asthma admissions, both before and after the legislation was passed. for the sample studied, before the legislation, admissions for asthma were increasing at a mean rate of 5.2% per year. the standard error for this estimate is 0.7% per year. after the legislation, admissions were decreasing at a mean rate of 18.2% per year, with a standard error for this mean of 1.79%. in both cases, the sample size is large enough to use a normal distribution. a) find a 90% confidence interval for the mean annual percent rate of change in childhood asthma hospital admissions in scotland before the smoke-free legislation. b)find a 90% confidence interval for the same quantity after the legislation

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
