Listed below are measured amounts of lead (in micrograms per cubic meter, or µg/m³) in the air. The EPA has established an air quality standard for lead of 1.5 µg/m³. The measurements shown below were recorded at a building on different days. Use the given values to construct a 95% confidence interval estimate of the mean amount of lead in the air. Is there anything about this data set suggesting that the confidence interval might not be very good? 5.40 1.10 0.43 0.79 0.76 0.90 Click here to view a t distribution table.

A genetic experiment with peas resulted in one sample of offspring that consisted of 437 green peas and 156 yellow peas. a. Construct a 90% confidence interval to estimate of the percentage of yellow peas. b. Based on the confidence interval, do the results of the experiment appear to contradict the expectation that 25% of the offspring peas would be yellow?
