A certain university has decided to introduce the use of plus and minus with letter grades, as long as there is evidence that more than 40% of the faculty favor the change. A random sample of faculty will be selected, and the resulting data will be used to test the relevant hypotheses.
1. If p represents the proportion of all faculty that favor a change to plus-minus grading, which of the following pairs of hypotheses should the administration test?
O H0: p = 0.4 versus Ha: p > 0.4
O H0: p = 0.4 versus Ha: p < 0.4

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
