The weights in grams of 10 males and 10 female juvenile ringnecked pheasants are given below. Males Females 1,386 1,66? 1,0?8 1,053 1,290 1,365 1,050 1,125 1,502 1,658 1,034 1,089 1,62? 1,725 1,023 1,03? 1,449 1,399 1,144 1,279 (a) Use a statistical test to determine if the population variance of the weights of the male birds differs from that of the females. (Use a = 0.10. Use 912 for the population variance of males and 922 for the population variance offemales.) State the null and altematjve hypotheses.
