Answer:

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

Step-by-step explanation:

We are given the following in the question:

Product A:

Number of people,

n_1 = 50

Number of people who received relief,

x_1 = 11

Proportion of people who received relief from product A =

p_A = \dfrac{x_1}{n_1} = \dfrac{11}{50} = 0.22 = 22\%

Proportion of people who did not received relief from product A =

1 = p_A = 1 - 0.22 = 0.78 =78\%

Product B:

Number of people,

n_2 = 100

Number of people who received relief,

x_2 = 14

Proportion of people who received relief from product B =

p_B = \dfrac{x_2}{n_2} = \dfrac{14}{100} = 0.14 =14\%

Proportion of people who did not received relief from product B =

1 = p_B = 1 - 0.14 = 0.86=86\%

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

LenKa [72]

Answer:

(B) (0.396, 1.712)

Step-by-step explanation:

From the information given;

Confidence Interval = 0.95

Significance Level = 1 - 0.95 = 0.05

The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:

= ( Beta ^- \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ), Beta^+ \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ))

From the regression coefficient, the estimated value of beta^  = 1.054

= (1.054 - t_{29,0.025} *(0.322), 1.054 + t_{29,0.025}*(0.322))

t_{229,0.025} = 2.0452\\\\ = \mathbf{(0.396, 1.712)}

If the polygons are similar, then the top side is equal to one half of the left side.
Since side (x -1) = 8, then x = 9.

As a salesperson for an electronic parts distributor, you are given two options for your salary structure. The first option has
kumpel [21]

Answer:

The amount of sale is approximately 5714.

Step-by-step explanation:

Let x be the sales made that will result to the same salary and let y be the same weekly salary.

We can represent both salaries as follows:

300 + 0.04x = y

100 + 0.075x = y

Subtracting the second equation from the first, we have:

200 – 0.035x = 0

0.035x= 200

x = 200/0.035

x ≈ 5714.

Therefore, the amount of sale is approximately 5714.
