L 8. Ballooning: Air Temperature How hot is the air in the top (crown) of a hot air bal
loon? Information from Ballooning: The Complete Guide to Riding the Winds, by
Wirth and Young (Random House), claims that the air in the crown should be an
average of 100°C for a balloon to be in a state of equilibrium. However, the tem-
perature does not need to be exactly 100°C. What is a reasonable and safe range
of temperatures? This may vary with the size and (decorative) shape of the balloon.
All balloons have a temperature gauge in the crown. Suppose that 56 readings (for
a balloon in equilibrium) gave a mean temperature ã = 97°C with sample standard
deviation s = 17°C.
(a) Compute a 95% confidence interval for the average temperature for which this
balloon will be in a steady-state equilibrium.
(b) If the average temperature in the crown of the balloon goes above the high end
of your confidence interval, do you expect the balloon will go up or

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. a.) increase the area of the base of the square pyramid by a factor of ten. b.) increase the height of the cylinder by a factor of ten. c.) increase the radius of the cone by a factor of ten. d.) increase the radius of a sphere by a factor of ten.
