An airline transports over 10 000 passengers daily, and the airline is curious whatproportion of their passengers use mobile boarding passes instead of paperpasses. They take a simple random sample of 80 passengers and find that 75% ofthem use mobile boarding passes. Based on this sample, which of the followingis a 90%, percent confidence interval for the proportion of passengers who useusemobile boarding passes?O [0.642 - 0.858]O (0.670 -0.830]O [0.625 - 0.875][0.637 -0.863]

Critical value: Using Excel formula "=NORM.S.INV(1-(0.1/2))", the z-value is obtained as 1.645.

Answered: An airline transports over 10 000…
