For the question below, identify the population parameter of interest and the sample statistic we might use to estimate the parameter. Weather Services International (WSI) records the data about the weather all over the world. We want to use these data What is the average temperature on January 12 in Los Angeles?

a. The relevant parameter is p, the proportion of days in a year with the average temperature the same as on January 12 for all years. We estimate it using the sample proportion of days in a year with the average temperature the same as on January 12 in Los Angeles for a few years.

b. The relevant parameter is p, the proportion of days in a year with the average temperature the same as on January 12 for all years. We estimate it using r, the correlation between the average temperature on January 12 with the year number for a random sample of a few years.

c. The relevant parameter is u, the average temperature in Los Angeles on January 12 for all recorded years. We estimate it using P, the sample proportion of days in a year with the average temperature the same as on January 12 in Los Angeles for a few years.

d. The relevant parameter is p, the correlation between the average temperature on January 12 with the year number. We estimate it using r, the correlation between the average temperature on January 12 with the year number for a random sample of a few years.

e. The relevant parameter is y, the average temperature in Los Angeles on January 12 for all recorded years. We estimate it using X, the sample average temperature on on January 12 in Los Angeles for a few years.
