5.30 A concern to public health officials is whether a
concentration of lead in the paint of older
homes may have an effect on the muscular development of young
children. In order to evaluate
this phenomenon, a researcher exposed 90 newly born mice to paint
containing a specified
amount of lead. The number of Type 2 fibers in the skeletal muscle
was determined 6 weeks
after exposure. The mean number of Type 2 fibers in the skeletal
muscles of normal mice of this
age is 21.7. The n=90 mice yielded y(mean)=8.8, s=15.3. Is there
significant evidence in the data
to support the hypothesis that the mean number of Type 2 fibers is
different from 21.7 using an
alpha = .05 test?
