In a blind taste test, do people prefer pate or dog food? to investigate, bohannon et al. (2010) presented 18 college-educated adults with unlabeled samples of dog food and four meat products meant for humans (duck liver mousse, pork liver pate, liverwurst, and spam). participants were asked to rank their preferences. two of the 18 participants ranked the dog food first, whereas other 16 participants chose one of the other items. based on these results, can we conclude that people are statistically significantly less likely to prefer dog food over all human food?

a. what is the null hypothesis? (what would you like to reject? )

your answer

b. what is the null distribution using the number of people who prefer dog food as the test statistic?

your answer

c. what is the p-value of the observation? (use one-sided null hypothesis test where only smaller values matter)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

b.my answer is b.

brainliest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
