Problem #8: A simple random sample of 70 basketball players is taken from different teams and their mean weight is found to be 240 pounds and the standard deviation of the population is 20 pounds. At the significance level a=0.01 test the claim that the average weight for all basketball players is 234 pounds. Note:Do Not test the claim! Compute only P value (consider as two-tailed test). What is P value? P = ?

Answers

the null and alterntive hypotheses are :

null hypothesis (Ho: mu = 234) against,

alternative hypothesis(H1 : mu is not equal to 234)

that is , it is two tailed .

solution) n =70, X = 240 Mo = 234 7 t = x - Mo S/ Jn = 240-234 20170 20509 So calculate t-value is 2.509. nove, p-value is th

The p-value is .01446.

The result is not significant at p < .01.
