0.5 is part of the confidence interval, and thus, it is reasonable to believe more than half of food delivery drivers eat some of the food they are delivering.
Step-by-step explanation:
95% confidence interval for the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
This means that we are 95% sure that the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
Is it reasonable to believe more than half of food delivery drivers eat some of the food they are delivering?
0.5 is part of the confidence interval, and thus, it is reasonable to believe more than half of food delivery drivers eat some of the food they are delivering.
We can start from the first sentence of the word problem and work from there.
First, the employee is working for 40 hours at $18.50 per hour. This means that for each hour, the employee is gaining $18.50 . This can be represented as $18.50 * 40 = $740 for their base pay.
Next, the employee works 8 hours of overtime at 1.5 * base pay (18.50). For each hour of overtime they work, they earn 1.5 * 18.50 = $27.75 dollars. Their earnings from overtime work for the week can be represented as
8 * 27.75 = $222
Because all the employee's hours are encompassed in overtime and base pay, we can add the two together to get
740 + 222 = $962.00 for their total pay for the week
