A hospital takes record of any birth that occurs there every day. On one day, the hospital reports that 35 of the 62 babies born were girls. Assuming that all of the parents did not have any gender selection procedures, there is a probability of 0.31 of getting these results by chance. Do these results have statistical significance at the 0.05 level of significance?

Step-by-step explanation:

You have to sum up three concepts, the cost before sales tax, the sales tax and the tip. The price before sales tax $11.75; the sales tax is the price times 8%, which $11.75 *8% = $11.75*8/100 = $11.75*0.08 = 0.94; and the itp is $2. Then, the equation is w = 11.75 + (0.08)(11.75) + 2, and the result is 14.69. So, the true statements are B and D.
