Question

This Question 1 pt 5 of 11 completel This Quiz: 11 pts possi Researchers conducted a field test and collected a sample of 10 adult female crab widers, each sitting on the yelow central part of a daisy. The chromatic contrast between each spider and the flower it was sitting on was measured numerically with a spectroradiometer, on which higher values indicate a greater contrast (and, presumably, easier detection by predators). The data for the 10 crab spiders are shown in the table below Complete parts a through e below 2 119 4 4 4 9 8 77 a. Sum e chrome contrast measurements for the 10 spiders with a stem-and-lea display Choose the correct answer below OC 0 0 OD 1 11 For w eb their care the stat can be by bed predators by being the respective contrastes on the OA Os 000 00:1.

Answer 1

Solution

1. Option (c )

The stem leaf plot of option c shows the plot of given data.

The last digit of the individual data value is treated as leaf.

The remaining digits are considered as stem

For example for the individual data value  

92

2- leaf

9- stem

For 119

9- leaf

11- stem

Similarly in this way the stem & leaf diagram can be drawn.

B. Given that birds can Oly see the crab which has contrast 70 or greater by bolding them

Option (a) is correct Which highlighted the contrast 77,92,119(contrast which are 70 or greater )

C. 3 of 10 observations fall on or above 70, one can inference that there is a probability of 30% that a bird detects a crab spider on the yellow part of a daisy
