Bill Alther is a zoologist who studies Anna's hummingbird (Calypteanna). A random sample of nine of these birds was caught, weighed, and released in a remote part of the Grand Canyon. The weights observed (in grams) were : 3.7 2.9 3.8 4.2 4.8 3.1 3.5 4.3 3.0 Let x be a random variable representing weights of Anna's hummingbirds in this part of the Grand Canyon. Assuming x has a normal distribution with sample standard deviation 0.648. The population mean is 4.55 grams. (a) Calculate the Sample Mean of the above mentioned data values. (b) Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less tham 4.55 grams? Establish the Null and AIternate Hypothesis. (c) Compute the Test statistics of the sample data using Student's t-distribution table. Take a= 0.05 (d) Find the P-value or range of P-values. (e) Conclude the test and interpret the result.

In soccer, serious fouls result in a penalty kick with one kicker and one defending goalkeeper. The accompanying table summarizes results from 306 kicks during games among top teams. In the table, jump direction indicates which way the goalkeeper jumped, where the kick direction is from the perspective of the goalkeeper. Use a 0.05 significance level to test the claim that the direction of the kick is independent of the direction of the goalkeeper jump. Do the results support the theory that because the kicks are so fast, goalkeepers have no time to react, so the directions of their jumps are independent of the directions of the kicks? E Click the icon to view the penalty kick data. Determine the null and alternative hypotheses. A. Ho: Jump direction is independent of kick direction. H: Jump direction is dependent on kick direction. O B. Ho: Goalkeepers jump in the direction of the kick. H,: Goalkeepers do not jump in the direction of the kick. O C. Ho: Goalkeepers do not jump in the…
