Answer:
Each Person:
-In tips: $2
-Food Bill: $7.50
Step-by-step explanation:
Let's find the tip amount for each person. $16 for the whole group. Each person will give in $2 for the tips, for a total of $16 in tips.
Now that tips are done, we must subtract the amount of tips from the food bill, to see how much each person pays. $76 - $16 = $60.
Divide 60 by 8 to get.. 60/8= 7.5.
With 7.5 as an answer, we can conclude that each person paid $7.50 for the food bill.

The answer is Equally Likely because there’s both 3 even numbers and odd numbers on a cube/dice.
The answer is 6,580,000 :)
Answer:
Z-test is a statistical test used to check weather two means are significant or not for unknown variance and large sample size.
Z = (M - μ) ÷ √(σ² / n)
where, M = Sample Mean = 66.075
μ = Population Mean = 90
σ² = Population Variance = 15
Now, Calculating the value of Z-test:
Z = (66.075 - 90) ÷ √(225 ÷ 40)
Z = -23.925 ÷ 2.37171
Z = -39.06936
The value of Z is -39.06936.
The value of p is < .00001 at 90% confidence level.
If the p-value is less than value of α, We accept the null- hypothesis otherwise reject.
The result is significant at p < .10.
Thus, we accept the null hypothesis.
