AI Thread Summary
For selecting a systematic sample from 760,000 customers with a target sample size of 250, a method involves calculating a sampling interval by dividing the total population by the desired sample size, resulting in an interval of approximately 3,040. The company would then randomly select a starting point within the first interval and continue selecting every 3,040th customer. The most significant expense likely limiting the sample size is labor costs associated with conducting the telephone interviews. Budget constraints necessitate careful consideration of these costs when planning the survey. Effective sampling methods can help maximize data collection within financial limits.

The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
