Answer: ? = 72

Step-by-step explanation:

We will set up a proportion to solve.

$\displaystyle \frac{?}{56} =\frac{45}{35}$

Now, we will cross-multiply.

? * 35 = 56 * 45

35? = 2,520

? = 72

It is generally believed that the mean value of the district's total SAT score distribution is equal to 1200 (the null hypothesi

g100num [7]

Answer:

The corresponding p-value, is p = 1

Step-by-step explanation:

The maximum score SAT score, n = 1,600

The mean of the district's total SAT score distribution = 1,200

The claim of one of the districts principal, is the that mean of the district's total SAT score distribution ≠ 1,200

Using proportions, we have;

p = 1,200/1,600 = 0.75

q = 1 - p = 0.25

The margin of error, E = Z√(p·q/n)

∴ E = 5% = Z×√((0.75 × 0.25)/1,600)

z = 0.05/(√((0.75 × 0.25)/1,600)) ≈ 4.61880

Therefore, the corresponding p-value, p = 1

"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50" can be written as $8 = ($1.50/ticket)*N.

Dividing both sides by ($1.50/ticket) results in

---------------------- = 5 1/3 tickets

($1.50/ticket)

or N < 5.
