H 200 201 Nest three questions are related to the following binary sample data 202 In the sample for question 13, the gender of employees is shown below [Male . 0, Female : 1) 203 0 0 0 0 204 205 206 207 208 209 210 211 0 212 213 214 215 216 220 22 222 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 15 The proportion of females in this sample is, 241 0.311 242 b 0.283 243 0.257 244 0.234 245 246 16 The confidence interval for the proportion employees who are female is 247 Use an error probability of 5%. 248 0.170 0.344 249 0.184 0.330 250 0.196 0.318 251 0.206 0.307 252 253 17 You decide to build a 95% interval estimate with a margin of error of 0.03 (3 254 percentage points). The minimum sample size to obtain the desired MOE is, 255 For planning value use the proportion obtained from the first sample. 256 717 257 815 258 926 259 1052 260 261 Next tro questions are related 262 18 To build an interval estimate for the proportion (percentage] of American 263 households who live paycheck-to-paycheck, a random sample 754 full-time 264 workers showed 647 live paycheck-to-paycheck. 265 The point estimate of the population proportion is. 266 0.858 267 0.825 268 0.793 269 0.763 270 271 19 In the previous question, build a confidence interval such that in 19 out of 20 cases 272 such intervals would capture the actual population proportion of households who 273 live paycheck-to-paycheck is 274 0.794 0.922 2751 0.818 0.898 276 C 0.833 0.883 277 0.843 0.874 278 279 20 The following is an interval estimate with a 95% confidence level for the proportion 280 of Indiana undergraduate students who plan to go to graduate school: 281 U 282 0.249 0.321 282 The size of the sample used to build this interval is 284 514 285 605 286 712 287 838 288 289 290
