You measure 20 backpacks' weights, and find they have a mean weight of 80 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, construct a 90% confidence interval for the true population mean backpack weight.Give your answers as decimals, to two places ________±____________ ounces

Confidence Interval (Breaking Distance of Cars)   Please collect the data and draw your assumptions.    Using the raw data  select the sample that represents the breaking distance of specific cars. Let X represent the number of cars whose breaking distance was less than 130 feet. Use this information to find the confidence interval for the percentage of cars whose breaking distance is less than 130 feet. n = ____________   x = ____________   State your assumption:    In words, define the random variable (sample proportion).   State the estimated distribution to use.     Find the Error and Confidence Interval How much area is in both tails (combined)? α = _____   How much area is in each tail? α/2 = _____ What is z?2 =     Construct the interval:  Error: _____  Confidence Interval: _____   Fill in the blanks on the graph with the area in each section.

What happens to the width of a confidence interval as we increase confidence level, i.e as we increase the confidence from 90% to 95%? The width decreases The width increases The width is not affected by the confidence level The standard deviation increases
