The daily dinner bills in a local restaurant are normally distributed with a mean of $28 and a standard deviation of $6. What ar
Degger [83]

Answer:

The minimum value of the bill that is greater than 95% of the bills is $37.87.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 28, \sigma = 6

What are the minimum value of the bill that is greater than 95% of the bills?

This is the 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

Z = \frac{X - \mu}{\sigma}

1.645 = \frac{X - 28}{6}

X - 28 = 6*1.645

X = 37.87

The minimum value of the bill that is greater than 95% of the bills is $37.87.

HELP ME please i need to solve this
nata0808 [166]

add 0+1+2+3+4 = 10

divide 10÷5 = 2

add 15+8+3+3+1 = 30

divide 30÷5 = 6

the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.

True or False?
oee [108]

Answer:

False

Step-by-step explanation:

y = 2x + 1

Substitute the point (4,3) into the equation and see if it is true

3 = 2(4) +1

3 =8+1

3 =9

This is false, so the point is not a solution
