Transcribed Image Text:Problem Solving: Caselet 2
Hydrangea is a flower that changes its color according the the pH of the soil.
The flower becomes blue when the pH of the soil is too acidic (pH below 5.5),
red when the pH of the soil is too basic (pH above 6.5), and purple when the
pH of the soil is exactly between 5.5 to 6.5. A landowner claims that the
average pH of their soil can produce perfectly consistent purple flowers with
a standard deviation pH of at most 0.5.
A flower cultivator thinks the standard deviation of the pH of the soil may be
greater than 0.5, so they tested 15 random sites from the land area. Use a
level of significance of a = 0.05.
