A recent study of 500 families showed that families owned an average of 2.71 TV's (TV). If sd(TVbar)=0.5, what is the conclusion from testing the following hypothesis (a=0.05): Ho: UTV = 1 Ha: UTV # 1 = cross out cross out cross out a. Since t>t*, reject HO at a 5% confidence level. Families do not have an average of 1 TV. O b. Since t>t*, reject HO at a 5% level of significance. Families do not have an average of 1 TV. O c. Since -t* <t<t*, do not reject HO at a 5% level of significance. Families may have an average of 1 TV. d. Impossible to determine based on 500 families. e. Since -t* <t<t*, do not reject H0 at a 5% confidence level. Families may have an average of 1 TV. cross out cross out
