7.2

1, 3, 5, 7 and 9 are odd and 0, 2, 4, 6, and 8 are even. Consider a 44-digit line from a random number table. Complete parts (a) and (b) below. a How many of the 44 digits would you expect to be odd, on average? 22 (Type an integer or a decimal. Do not round.) b. If you actually counted, would you get exactly the number predicted in part (a)? Explain. O A. No, because while a sample might have exactly the number predicted, a sample could also have smaller or larger numbers due to variation from sample to sample O B. Yes, because the sample is sufficiently large that the sample proportion will be the same as the population proportion O C. No, because samples will never have exactly the number predicted due to variation from sample to sample O D. Yes, because samples will always match the population proportion
