Your start-up business is looking into the energy usage in the community of south lawndale. your sample size is 12 months. use t
Aleonysh [2.5K]

The confidence interval at 95% level is

7106.87 <  μ< 14255.27

<h3>What is meant be mean and standard deviation?</h3>

The ratio of sum of observations to the total number of observation is known as mean. It is one of the central tendency in the statistics. It gives an idea about the central value present in the data. The most sensitive measure of central tendency is mean. It is very easy to calculate. Mean playa a crucial role in daily life. The two types of means are Arithmetic mean and Geometric mean.

Standard deviation is a measure in the statistics. The amount of variation of a set of values is known as standard deviation. Standard deviation is denoted by σ.

As per given data

90% confident level for amount of electricity used in community of Austin is

X-tx/2(n-1)s/√n < μ < X+ tx/2(n-1)s/√n

Here , n=12 ,  X=10681.07 , s=6893.87

Margin of error = tx/2(n-1)s/√n

=(1.796×6893.87)/√12

=3574.1996

=3574.19(approximately)

Therefore, 90% CI is,

10681.07-3574.19 ≤ μ<10681.07+3574.19

7106.87 <  μ< 14255.27

Use the permutation formula to solve a problem when n = 15 and r = 4.
barxatty [35]

nPr =  \frac{n!}{(n - r)!}

15P4 =  \frac{15!}{(15 - 4)!} = \frac{15!}{11!} \\  = \frac{15 \times 14 \times 13 \times 12 \times 11!}{11!} \\ 15 \times 14 \times 13 \times 12 = 32760

Camille is working in craft class to create new pillows for her room. Each pillow will be made from exactly 36 in2 of material.
Ann [662]

The best design for Camille is the one in which the area matches the total of material she wants to use for each pillow.

<h3>What should Camille consider for her design?</h3>

Camille's main restriction is the material per pillow since she needs every pillow to use only 36 inches of material. Due to this, she needs to make sure the design meets this requirement.

<h3>How to determine how much material each design requires?</h3>

The best method for this is to calculate the area of the design by using the sides. Here are the most common formulas:

  • Triangular design: Base x height/ 2
  • Squared or rectangular design: side x side
  • Circular design: A = π r²

Based on this, the best design is the one that adjusts to the material available.

Note: This question is incomplete because there is no information about the designs; due to this, I answered it based on general knowledge.
