Stats Problem for Homework I was wondering what kind of hypothesis testing i should use for this question? Do female college students pay more for haircuts on average than male college students? Conduct a test of this question using a 3 percent level of significance. The following data were gathered from Math 10 students taking class Fall 2008.: Males: 12, 12, 10, 60, 14, 8, 0, 15, 15, 0, 0, 10, 0, 10, 12, 9, 17, 17, 14, 22, 20, 25 Females: 25, 20, 15, 70, 36, 50, , 8, 9, 20, 8, 55, 55, 90, 25, 8, 50, 50, 20, 17, 20, 40, 25, 35, 25, 60, 50, 40, 15, 10, 5 According to my friend, they believe H-null is mu1=mu2, and that it is a two tailed test. Is that right?

Help with Statistics I can't seem to solve this problem. And it's killing me because its bascially worth like 10% of my homework. :( A blood bank asserts that a person with type O blood and a negative Rh factor (Rhâˆ') can donate blood to any person with any blood type. Their data show that 44% of people have type O blood and 17% of people have Rhâˆ' factor; 52% of people have type O or Rhâˆ' factor. Find the probability that a person does NOT have both type O blood and the Rhâˆ' factor. My question is if someone could guide me show me the steps to solve this problem?
