My Notes Ask Your Teacher How hat is the air in the top (crown) of a hot air balloon? 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 temperature does not need to be cactly 100°C. What is a reasonable and safe range of temperatures? This range may vary with the size and decorative) shape of the balloon. All balloons have a temperature gauge in the crown. Suppose that readings (for a balloon in equilibrium) gave a mean temperature of 97°C. For this balloon, 16°C (a) Computea 95% confidence interval for the average temperature at which this balloon will be in a steady-state equilibrium (Round your answers to one decimal poce) lower limit upper limit (b) If the average temperature in the crown of the balloon goes above the high end of your confidence interval, do you expect that the balloon will go up or down?

Answer 1

a.)

T=97,0 = 16, n = 53

critical value at 95 % confidence(Z_a/2)=1.96

Confidence interval is given by:

T + 2a/2 * = 16 = 97 1.96 * V53 = 97 = 4.31

= (92.69, 101.31) hence, lower limit = 92.7 upper limit = 101.3

= (92.69, 101.31) hence, lower limit = 92.7 upper limit = 101.3

b.)

it will go up because hot air will make the balloon rise.
