WILL MARK BRAINLEST California's traffic People love living in California for many reasons , but traffic isn't one of them . Based on a random sample of 572 employed California adults, a 90 % confidence interval for average travel time to work for all employed California adults is 23 minutes to 26 minutes
(A) Interpret the confidence level?
(B) Name two things you could do to reduce the margin of error. What drawbacks do these actions have?
(C) Describe how no responses might lead to bias in this survey. Does the stated margin of error account for this possible bias?
(Each one is a question)

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
