A simple random sample from a population with a normal distribution of 100 body temperatures has a x= 98.30 F and a s=0.61 F. Construct a 98% confidence interval estimate of the standard deviation of body temperature of all healthy humans.

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
