Math 240. The drop down choices to identify the population parameter include( The number of customers in the sample that prefer a window seat, the number of customers sampled, the proportion of all customers in the sample who prefer the window seat, or the proportion of all customers who prefer the window seat). The drop down choices for what condition for using z- distribution is met include: ( A sample random sample of more than 30 customers was taken, the sample taken was a simple random sample, or the true population is known). Lastly, what conclusion can be drawn from the data drop down choices include: ( insufficient evidence exists to conclude or sufficient evidence exists to conclude).
