A recent study by Munro et al found that 15% of college freshman were not happy with their choice of major. A random sample of 100 college juniors found that 10% were not happy with
their major. Is there sufficient evidence to suggest that the proportion of students not happy with
their major is smaller among juniors than freshman? Use alpha = .05.

Step-by-step explanation:

42

step-by-step explanation:

256/6=42

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
