The crab spider. Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To te this, Heiling et al. (2003) gave 33 bees a choice between 2 flowers: one with, and one without a crab spider. In 23 of the 33 trials, the bees picked the flower that had the spider. In the othe trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z,0,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE). State your answer for the value of P to three decimal places, and include the leading zero. Do all of the math in Excel • DO NOT round the value of Z. • Substitute the cell (e.g. B1) for Z in the formula for P.

Question
The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 33 bees a choice between 2 flowers: one with, and one without a crab spider. In 23 of the 33 trials, the bees picked the flower that had the spider. In the other trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z.O,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE). State your answer for the value of P to three decimal places, and include the leading zero. . Do all of the math in Excel • DO NOT round the value of Z. • Substitute the cell (e.g. B1) for Z in the formula for P.
