In a study at 422 nonproﬁts nationwide, 34 indicated that turnover has been the biggest employment challenge at their organization. Complete parts (a) through (c).a. construct a Bb’ilh conﬁdence Interval ror tne population proportlon ot nonproﬁts that Indicate turnover as the biggest employment challenge at tnelr organlzatlon. s r: 5 (Type integers or decimals. Round to three decimal places as needed.) b. Interpret the interval mnstructed in part (a). Choose the correct answer below. 0 A. With 5% conﬁdence. the proportion of nonproﬁts that indicate turnover as the biggest employment challenge at their organization in the sample is in this interval.0 B. With 5% conﬁdence. the proportion of nonproﬁts that indicate turnover as the biggat employment challenge at their organization in the population is in this interval. 0 C. With 95% conﬁdence, the proportion ofnonproﬁts that indicate tumover as the biggest employment challenge at their organization in the sample is in this interval.0 D. With 95% conﬁdence, the proportion ofnonproﬁts that indicate tumover as the biggest employment challenge at their organization in the population is in this interval. 6. If you wanted to conduct a follow-up study to estimate the population proportion of nonproﬁts that indicate tumover as the biggest employment challenge at their organization to within 1 0.02 with95% conﬁdence, how many nonproﬁts would you survey? A sample of i—i nonproﬁts should be surveyed. (Round up to the nearest intlecer.i
