A temperature survey is done to see if this year temperature is consistent with previous years. Suppose, the 4 entries recorded for the seasons, and the temperature are historically in a 4:6:3:1 proportion and in a survey the following counts are found
Observed: Spring (65); Summer (74); Fall (57); Winter (39)
How do we do a test of hypothesis to find if this survey result has the same proportions as historically.
