In your random sample of 25 Chips Ahoy bags, you find a mean of 985 chips per bag, with a standard deviation of 10 chips. Run a

two-tailed significance test to see if you have evidence supporting Nabisco’s claim that Chips Ahoy bags contain about 1000 chips. The p-value for the test statistic is...

Answer:

The p -value is less than 0.001.

Step-by-step explanation:

Given information:

Sample size = 25 chips

Sample mean = 985

Sample standard deviation = 10

Let as assume that sample is distributed normally.

The formula for test statistic

t=\frac{\overline{x}-\mu}{\frac{s}{\sqrt{n}}}

where,

\overline{x} is sample mean

μ is population mean.

s is sample standard deviation.

n is sample size.

The value of test statistic is

t=\frac{985-1000}{\frac{10}{\sqrt{25}}}

t=\frac{985-1000}{\frac{10}{\sqrt{25}}}

t=-7.5

The p-value is

p=2\times p(t

Therefore the p -value is less than 0.001.

just olya [345]

A. Independent variable: number of rubber stamps n sold. Dependent variable: F(n), the total sales.

B. Only whole numbers. It is impossible to have negative and/or fractional stamps.

C. F(n) = $4.95n, which is 4.95 times n.

So, plugin 5 for n

f(5)= \$4.95(5)

F(n) = $24.75

M∠a=(48−x)°m∠b=(9x−38)°m∠c=90°
Pachacha [2.7K]

<u>The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.</u>

Answer:

<em>x = 10</em>

Step-by-step explanation:

<u>Internal Angles of a Triangle</u>

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10

Hey! This is due at like 11 pm!
rewona [7]

Answer:

7

Step-by-step explanation:

Use the Pythagorean Theorem

a^2 + b^2 = c^2

a and b are either opposite or adjacent

c is the hypotenuse.

1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.

2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.

3. Plug in the numbers. 24^2 + b^2 = 25^2

4. Solve:

24^2 + b^2 = 25^2

576 +b^2=625

b^2 = 625-576

b^2 = 49

\sqrt{b^2} = \sqrt{49}

b = 7

Hope this helps! Lmk if you have questions.

Jude says that the volume of a square pyramid with base edges of 9.7 in and a height of 9 in is equal to the volume of a cylinde
earnstyle [38]

Answer:

The correct option is;

Yes, his calculations are correct and the volumes for figures are equal

Step-by-step explanation:

The volume, V, of a square  (of side s) pyramid of height h = \frac{1}{3} \times s^2 \times h

Where:

s = 9.7 inches

h = 9 inches

We have;

V = \frac{1}{3} \times 9.7^2 \times 9 = \frac{1}{3} \times 94.09 \times 9 = \frac{1}{3} \times 846.81 = 282.27 \approx 282 \ in^3

The volume, V_c, of a cylinder of radius r = Base area × Height, h = (π×r²)×h

Where:

Base area = π×r²

r = Radius of the cylinder = 5.47 inches

h = Height of the cylinder = 3 inches

V_c = π × 5.47² × 3 = π × 29.9209 × 3 = π × 89.7627 = 281.998 ≈ 282 m³

Therefore, Jude is correct.
