AP stat refence

  1. Apr 20, 2005 #1
    i dont know which data is the slope and which is the y-intersect

    Researchers at the university of Denver infant study center wondered if temperature might influence the age at which babies learn to crawl. Perhaps the extra clothing that babies wear in cold weather would restrict movement and delay the age at which they start crawling. Data were collected on 208 boys and 206 girls.
    Parents reported the month of the baby's birth and the age (in weeks) at which their child first crawled. The table gives the average temperature (F) when the babies were 6 months old and average crawling age(in weeks) for each month of the year. Is there evidence of an association between temperature and crawling age.

    data 6-month temperature and average crawling age were given.

    The description of your data is too vague. Perhaps if you post your table of data with headings, we would have a better chance of helping on this one..
