102 adult tickets were sold.

Step-by-step explanation:

Let,

Adult tickets = x

Children tickets = y

According to given statement;

x+y=146 Eqn 1

8x+5y=1036 Eqn 2

Multiplying\ Eqn\ 1\ by\ 5\\5(x+y=146)\\5x+5y=730\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(8x+5y)-(5x-5y)=1036-730\\8x+5y-5x-5y=306\\3x=306\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{306}{3}\\x=102\\

102 adult tickets were sold.

A supervisor records the repair cost for 14 randomly selected refrigerators. A sample mean of $79.20 and standard deviation of $
Nitella [24]

Answer:

( $74.623, $83.777)

The 90% confidence interval is = ( $74.623, $83.777)

Critical value at 90% confidence = 1.645

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = $79.20

Standard deviation r = $10.41

Number of samples n = 14

Confidence interval = 90%

Using the z table;

The critical value that should be used in constructing the confidence interval.

z(α=0.05) = 1.645

Critical value at 90% confidence z = 1.645

Substituting the values we have;

$79.20+/-1.645($10.42/√14)

$79.20+/-1.645($2.782189528308)

$79.20+/-$4.576701774067

$79.20+/-$4.577

( $74.623, $83.777)

The 90% confidence interval is = ( $74.623, $83.777)
