Here is me with more issues. Melissa’s birthday is next week and she has been receiving cards in the mail with different amounts of money. She has received five gift cards with the following amounts: $10, $20, $25, $30, and $40. If Melissa receives one more card in the mail with $25, what will the standard deviation do, decrease, increase, or stay the same? The picture is also there!
