8) On June 11, 2004, tennis player Andy Roddick delivered the fastest tennis
serve ever recorded by radar. If the radar gun being used that day sent out signals
every 0.1 second and recorded the ball moving 22.44 feet between flashes, how fast
was Andy Roddick's serve in Miles per Hour?
A) Fill in the blanks with their proper units of measurement, The labels for cancellation should be arranged
diagonally, positioning their numbers correctly for multiplication horizontally.

NOTAarrow_forwardIf there is no seasonal effects on human births, we would expect equal numbers of children to be born in each season (winter, spring, summer, and fall). A student takes a census of her statistics class and finds that of the 120 students in the class, 25 were born in winter, 35 in spring, 32 in summer, and 28 in fall. She wonders if the excess in the spring is an indication that births are not uniform throughout the year. What is the chi-square statistic? What is the p-value? ( 3 decimal places) What is your decision? What is your conclusion in context?arrow_forward
