20 The Transportation Security Administration (TSA) is responsible for airport safety. On some flights, TSA officers randomly select passengers for an extra security check before boarding. One such flight had 76 passengers- 12 in first class and 64 in couch class, TSA officers selected an SRS of 10 passengers for screening. Let p be the proportion of first-class passengers in the sample.
What effect does violating the 10% condition have on the standard deviation of the sampling distribution of p?
