• Press @@@OK@@@ to obtain the following results: Confidence intervals The application 6. Conf Interval can be accessed by using ,Ù-@@@OK@@@. The application offers the following options: These options are to be interpreted as follows: 1. Z-INT: 1 µ.: Single sample confidence interval for the population mean, µ, with known population variance, or for large samples with unknown population variance. 2. Z-INT: µ1−µ2.: Confidence interval for the difference of the population means, µ1- µ2, with either known population variances, or for large samples with unknown population variances. 3. Z-INT: 1 p.: Single sample confidence interval for the proportion, p, for large samples with unknown population variance. Page 16-7
