Answer:
The answer is $523
Step-by-step explanation:
Because well think about it at first he has $123 and there r four players and so they each give $100 every time he wins so that will be $523 that he will have after.
The tax he has to pay is $4.95
The total bill would be $94.95
42.081 * 99.91 ≈ 42 * 100 ≈ 4200

Step-by-step explanation:
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.
