Answer:

The ratio is 34/22, or in simplest form, 17/11.

Step-by-step explanation:

We write the ratio with the number of rolls greater than three on top and the number of rolls less than or equal to 3 on bottom:

34/(56-34)

We have to subtract 34 from 56 to find out how many rolls were less than or equal to 3.

34/22

Both are divisible by 2, so we have 17/11.

Significance level : \alpha:1-0.95=0.05α:1−0.95=0.05

Critical value : z_{\alpha/2}=1.96

Hence the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)(10.1989, 11.0011)
