MrRissso [65]

Answer:

a) The 90% confidence interval is 0.575\leq \pi\leq 0.701

b) The margin of error is 0.063.

Step-by-step explanation:

We have to construct a 90% confidence interval for the proportion of students enrolled in college or a trade school within 12 months of graduating from high school in 2013.

We have a sample of 160 students, and a proportion of:

p=X/N=102/160=0.6375

The standard deviation is:

\sigma=\sqrt{\frac{p(1-p)}{N}}=\sqrt{\frac{0.6375*0.3625}{160}}=0.038

As the sample size is big enough, we use the z-value as statistic. For a 90% CI, the z-value is z=1.645.

Then, the margin of error is:

E=z\cdot\sigma=1.645\cdot 0.038=0.063

Then, the 90% confidence interval is:

p-z\cdot \sigma\leq \pi\leq p+z\cdot\sigma\\\\0.638-0.063\leq \pi\leq 0.638+0.063\\\\0.575\leq \pi\leq 0.701
