1. California least terns are found along the Pacific coast. A researcher group is studying a population of the birds living off the coast in Santa Barbara. The researchers survey several 100 m areas once a month for seven months and count the number of birds seen in each plot of land. The table in Excel is the data recorded for plots A-E for each of the seven months. Using the table provided, solve the summation notation for each of the following. (3pts each) a. Xij i= 2 b. 2 + I'M X1j c. Consider the table a single data sample and calculate the following descriptive statistics listed on Excel. (1pt each) Least terns are well documented in Santa Cruz (Central California), with a mean of 34.6 birds per 100 m- area. Does Santa Barbara have a significantly higher abundance of birds than Santa Cruz? d. Write out the null and alternative hypotheses: (2pts) e. Is it one- or two-tailed? (1 points) f. Provide/calculate the values listed in Excel. (1pt each) g. In no more than 2 sentences, what are your statistical and biological conclusions? (4pts) h. Construct a 90% confidence interval for the mean of Plot C. (6 pts) i. Construct a 95% confidence interval for the mean of Plot D. (6 pts)\f
