Researchers are measuring the number of days lettuce seeds take to germinate. The box-and-whisker plot summarizes the data. What can you conclude from the box-and-whisker plot?

A) 25% of the seeds took more than 6 days to germinate.
B) 50% of the seeds took more than 8 days to germinate
C) 25% of the seeds took less than 5 days to germinate.
D) The median number of days for the seeds to germinate was 3.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
