An airline would like information on which seat is preferred by customers. The airline assumes the majority of customers prefer the window seat, and is looking for evidence to support that claim. The results of a simple random sample of customer seat preference is shown below.

window seat 208

observations 400

confidence level 0.9

critical value 1.28

test statistic (z) 0.8

p-value 0.2119

Identify the popular parameter? (the # of customers in sample who prefer a window seat, the # of customers sampled, the proportion of all customers in the sample who prefer window seat, or the proportion of all customers who prefer window seat)

what condition for using z-distribution is met?

level of significance?

null hypothesis H0?

alternative hypothesis?

should h0 be rejected or does h0 fail to be rejected?

what conclusion can be drawn from this data? (insufficient data exists or sufficient data exists?)
