You need to use the cross product method to find your answer :
1 pizza = 2 ½ cups
3 pizzas = × cups
((2 ½) • 3) ÷ 1 = × cups
7 ½ ÷ 1 = × cups
7 ½ = × cups
⇨ So your answer is: You would need to use 7 ½ cups of flour to make 3 handmade pizzas!
There you go. I really hope this helped, if there’s anything just let me know! ☻
Answer:
(B) The correct interpretation of this interval is that 90% of the students in the population should have their scores improve by between 72.3 and 91.4 points.
Step-by-step explanation:
Confidence interval is the range the true values fall in under a given <em>confidence level</em>.
Confidence level states the probability that a random chosen sample performs the surveyed characteristic in the range of confidence interval. Thus,
90% confidence interval means that there is 90% probability that the statistic (in this case SAT score improvement) of a member of the population falls in the confidence interval.
