A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 421 gram setting. It is

Anastaziya [24]

Answer:

The p-value is approximately 0.0508

Step-by-step explanation:

The given parameters are;

The expected mass of banana chips bag filled by the machine, μ = 421 gams

The number of bags in the sample of bags filled by the machine, n = 26 bags

The mean mass of the bags in the sample, $\overline x$ = 413 grams

The standard deviation of the mass in the bags, s = 24 grams

The level of significance, α = 0.02

The null hypothesis, H₀; μ = 421 grams

The alternative hypothesis, Hₐ; μ < 421 grams

The test statistic is given as follows;

$t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}$

We get;

$t=\dfrac{413-421 }{\dfrac{24}{\sqrt{26}}} \approx -1.6996731712$

The t-value = -1.6996731712

The degrees of freedom df = n - 1 = 26 - 1 = 25

From an online source, we get the critical-t = 2.166587

The p-value is obtained using an online source as p(t ≤ -1.6996731712) = 0.0508

From the p-value table, we get

0.05 < p < 0.1

Describe five ways to represent a function ?

Over [174]

1. A function can be represented verbally. For example, the circumference of a square is four times one of its sides.

2. A function can be represented algebraically. For example, 3x+6 3 x + 6.

3.A function can be represented numerically.

4. A function can be represented graphically.

I only found four, hopefully this helps.

A company makes gift boxes in different sizes following the pattern shown below. What is the volume of the fourth gift box to th

AVprozaik [17]

The volume of the fourth box is of 410.1 cubic inches.

---------------------

The volume of a rectangular prism is given by the base area multiplied by the height, that is:

$V = A_bh$

---------------------

For the first three boxes, the height is constant at 9 inches.
At the base, the edge length is multiplied by 1.5 each time, as $\frac{4.5}{3} = \frac{3}{2} = 1.5$ , thus, for the fourth box, the edge length, in inches, will be of $4.5 \times 1.5 = 6.75$
