Jamie recorded the time it took 25 students to complete a mathematics test. She created a histogram and a stem-and-leaf plot to represent the data. To determine the median of the data set, Jamie analyzed the -

a) histogram because it showed each value in the set of data

b) stem-and-leaf-plot because it showed each value in the set of data

c) histogram because the median is always the bar with the greatest height

d) stem-and-leaf-plot because the median is always the "leaf" that
appears most often

Write the standard form of an equation with (see picture below)

Isaac wants the equation below to have no solution when the missing number is placed in the box. which number should he place in the box?

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?
