A 90% confidence interval for the average salary of all CEOs in the electronics industry was constructed using the results of a random survey of 45 CEOs. The interval was ($124,443, $140,235). Give a practical interpretation of the interval. O 90% of the sampled CEOs have salaries that fell in the interval $124,443 to $140,235. O 90% of all CEOs in the electronics industry have salaries that fall between $124,443 to $140,235. O We are 90% confident that the mean salary of the sampled CEOs falls in the interval $124,443 to $140,235. O We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $124,443 to $140,235.
