A study of young children was designed to increase their intake of whole-grain, rather than regular-grain, snacks. At the end of the study, the76children who participated in the study were presented with a choice between aregular-grainsnack and awhole-grainalternative. Thewhole-grainalternative was chosen by53children. You want to examine the possibility that the children are equally likely to choose each type of snack.

Perform the significance test. (Use= 0.01. Round your test statistic to two decimal places and yourP-value to four decimal places.)

z=_______

P-value=_______

How do I solve for this without using a calculator? Thank you.
