Question
Ciara, an ornithologist (a person who studies or is an expert on birds.), has 4 bird feeders at separate locations. She wonders if birds are equally likely to visit each of the feeders (each expected proportion to be 25%). She recorded data for a sample of 350 recent visits. Here are the results: HINT: Use Rguroo: Analysis-> analytics-> Goodness of Fit: Make 4 levels (categories) - complete observed counts using the values in the table - for null probabilities check Ho Feeder #1 #2 #3 Observed visits 80 90 92 If Ciara performs a goodness-of-fit, can she determine if these results suggest that birds visit one specific feeder is different or the same from the other feeders. Test at 5% significance level. Ho P1 P2 P3 = P4 = 25% Ha: At least one proportion is different than expected. a) The value of the observed test statistic is Xobserved Round to two decimal places. #4 88 b) The Xcritical c) Result: Since Xobserved the null. (use the operations ">" or "<" or "="). Round to two decimal places. Xcritical we fail to reject
