The types of browse favored by deer are shown in the following table. Using binoculars, volunteers observed the feeding habits of a random sample of 320 deer. Type of Browse Plant Compositionin Study Area Observed Number of DeerFeeding on This Plant Sage brush 32% 103 Rabbit brush 38.7% 134 Salt brush 12% 38 Service berry 9.3% 23 Other 8% 22 Use a 5% level of significance to test the claim that the natural distribution of browse fits the deer feeding pattern. State the null and alternate hypotheses. A) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) B) Estimate the P-value of the sample test statistic. C) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis that the population fits the specified distribution of categories?
The types of browse favored by deer are shown in the following table. Using binoculars, volunteers observed the feeding habits of a random sample of 320 deer.
Type of Browse | Plant Composition in Study Area |

Sage brush | 32% | 103 |
Rabbit brush | 38.7% | 134 |
Salt brush | 12% | 38 |
Service berry | 9.3% | 23 |
