Consider dataset “juul” from library “iswr”.
a. are the means of igf1 equal among tanner groups at 5% level?
b. use the six step process to test statistical hypotheses for this research problem.
note: you need to convert tanner from numeric to factor type and ignore all the nas.

building and maintaining the topology is difficult and time consuming. the chance of redundant connections is high, which adds to the high costs and potential for reduced efficiency.

explanation:

can you include the statments that complete the question ?
