According to a study by the american pet food dealers association, 63 percent of u. s. households own pets. a report is being prepared for an editorial in the san francisco chronicle. as a part of the editorial a random sample of 300 households showed 210 own pets. does this data disagree with the pet food dealers association data? use a .05 level of significance. discuss how you arrived at the results. think about how many of your friends or relatives are pet owners. do these people seem to be representative of the pet food survey respondents?

2.511 lies in the rejection region, so we will reject the null hypothesis.

Step-by-step explanation:

Since the null and alternate hypothesis are :

Since there is 0.05 level of significance,

So, there will be two tail test:

As we know that

z = -1.96 or z = 1.96

If the test statistic does not fall in the range of -1.96 to 1.96, we will reject the null hypothesis.

So, it becomes,

Since 2.511 lies in the rejection region, so we will reject the null hypothesis.

Hence, People does not seem to be representative of the Pet Food survey respondents.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
