Answer:
16.643 Kilograms
Step-by-step explanation:
Total means the sum of the number in this situation so first, you add
1.453 kg and 3.8 kg = 5.253 kg
then you add
5.253 kg and 11.39 kg = 16.643 kg
so the answer is 16.643 kilograms.
Calculating the z scores for each student:
zTara = (52-64 )/8 = -12/8 = -1.5
zJamal = (82-64)/8 = 18/8 = 2.25
zSamuel = (66-64)/8 = 2/8 = 0.25
From the z score table, the probability of Tara's score being greater than -1.5 is 0.0668. Therefore, the percentage is 0.0668*100 = 6.68% which means that around 7% of the students got a better mark than Tara, with 93.32% of the students scoring lower than her.
The probability of Jamal's score being greater than 2.25 is 0.0122, therefore the percentage is 0.0122*100 = 1.22% implying that around 1% of the students got a better mark than Jamal.
The probability of Samuel's score being greater than 0.25 is 0.4013, therefore the percentage is 0.4013*100 = 40.13% which means that around 40% of the students got a better mark than Samuel, with 59.87% of the students scoring lower than him.
