Question

Sarah works for the Urban Pollination Project at UW. Five years ago, 25% of urban gardens were visited by native bees, and Sarah would like to show that this proportion is different now than it was five years ago. Suppose Sarah calculates a p-value of 178. What is the best conclusion at a significance level of 0.057?

a. Sarah does not have evidence that the proportion of urban gardens visited by native bees has not changed.
b. Sarah has evidence that the proportion of urban gardens visited by native bees has not changed
c. Sarah has evidence that the proportion of urban gardens visited by native bees has changed
d. Sarah does not have evidence that the proportion of urban gardens visited by native bees has changed

Answer 1

The answer is "Option a".

Explanation:

The value of p
`= 0.178`

The significance level
`= 0.057`

Hypothesis:

`H_0 -p=0.25\\\\H_1 -p \\eq 0.25\\\\\to 0.178 > 0.057` that is p-value
`> \alpha`

therefore we don't reject
`H_o`
