In the previous two assignments, operands are limited to non-negative values. Without changing much of the previous implementations, you can realize for negative operand values by transforming the operations with non-negative operand values. For instance, "-12345" + "-12345" can be expressed "0" - ("12345" + "12345"). This means that at an addition operator the two negative operand values are converted to positive values, i. e., negative sign are removed before applying addition operation followed by a subtraction. You can manipulate other cases in similar ways. Extend the previous two operators by adding a logic each to transform the formula. Use the supplied check logic. Set seed 789 for your submission. You can submit up to three times.

The survey of study habits and attitudes (ssha) is a psychological test that measures the motivation, attitude toward school, and study habits of students, scores range from 0 to 200. the mean score for u. s. college students is about 115, and the standard deviation is about 30. a teacher who suspects that older students have better attitudes toward school gives the ssha to 55 students who are at least 30 years of age. the mean score is 113.2. assume the population standard deviation is 30 for older students what is the margin of error for a 95% confidence interval for the population mean score for a. older students? b. compute the 95% confidence interval for the population mean score for older students. c. compute the 99% confidence interval for the population mean score for older students. d. compute the 88% confidence interval for the population mean score for older students.
