Answer

Explanation:

Step1: Calculate the mean for name - brand

First, sum the number of chips for name - brand: $22 + 27+25 + 20+29+33+25+23+30+22+26+21+20=313$. There are 13 data points. The mean $\bar{x}_{name}=\frac{313}{13}\approx24.08$.

Step2: Calculate the mean for store - brand

Sum the number of chips for store - brand: $15 + 22+21+28+24+26+19+23+27+33+24+28+17 = 287$. There are 13 data points. The mean $\bar{x}_{store}=\frac{287}{13}\approx22.08$.

Step3: Compare the means

Since $\bar{x}{name}\approx24.08$ and $\bar{x}{store}\approx22.08$, the name - brand appears to have more chips per cookie.

Answer:

C. Yes. The name brand appears to have more chips per cookie.
