1. An election poll reported that a candidate had an approval rating of 59% with a margin of error E OF 2. CONSTRUCT A CONFIDENCE INTERVAL FOR THE PORPORTION OF ADULTS WHO APPROVE.

2.You are given the sample mean and the sample standard deviation. Use this information to construct the 90% and 95% onfidence intervals for the population mean. Which interval is wider? A random sample of 41 gas grills has a mean price of \$626.50 and a standard deviation of \$59.70

3. find the minimum sample size n needed to estimate u for the given values of c,s and E. c=.95, s=7.5, E=1

4. you randomly select and measure the contents of 10 bottles of cough syryp. The results are shown (fluid ounces.)

Assume teh sample is taken from a normally distributed population. Construct 80% confidence intervals for a the population variance and b the population standard deviation.

Results--> 4.216 4.292 4.241 4.184 4.285 4.265 4.246 4.224 4.237
