Answer:

The appropriate alternative hypothesis is, Hₐ: p₁ - p₂ > 0.

Step-by-step explanation:

In this case it is provided that Triclosan is a compound often added to products such as soaps, lotions, and toothpaste.

Since the compound is antimicrobial its corporate producer maintained that it should help prevent staph infections among people who use products containing the compound.

But a scientist wants to test whether the compound actually is associated with higher incidence of staph infection.

That is he wants to determine whether people with a detectable level of triclosan have higher rates of carrying the staph bacteria than people without triclosan.

Denote:

Group 1: people with a detectable level of triclosan

Group 2: people without a detectable level of triclosan

To test this the hypothesis can be defined as follows:

H₀: The proportion of people with a detectable level of triclosan does not have higher rates of carrying the staph bacteria than people without triclosan, i.e. p₁ - p₂ ≤ 0.

Hₐ: The proportion of people with a detectable level of triclosan have higher rates of carrying the staph bacteria than people without triclosan, i.e. p₁ - p₂ > 0.

Thus, the appropriate alternative hypothesis is, Hₐ: p₁ - p₂ > 0.

Can someone explain to me how to do this and what the answer is

Mashutka [201]

Since lines TS and GF are congruent that means that they are the same length.

Use the equation 12=2x-16 and simplify and you get:

X=14 since the side length is 12

If r=4 units and x = 8 units then what is the volume of the cylinder shown above use 3.14 for TT and round your answer to the ne

BARSIC [14]

To answer this you will use the formula V = pi x radius ^2 x height. The substitution for this would be 3.14 x 4^2 x 8. The approximate answer is 401.92 cubic units. 3.14 is an approximation of pi.

Note: It does not say that x is the height, but this is the only piece of information missing without an obvious label, so I am using it as the height.

The local high school hosted a hockey tournament. Tickets were sold before the tournament and at the door. When reviewing the ti

stiv31 [10]

The first thing we must do for this case is to define variables: x: number of tickets sold before the tournament. y: number of tickets sold at the door. The system of equations that adapts to this situation is given by: x + y = 820 x-y = 80 Answer: The correct options are: option 2 option 3 option 5

Answer:

a = $8
s = $5

Step-by-step explanation:

When the coefficients don't lend themselves to solution by substitution or elimination, then Cramer's Rule can be useful. It tells you the solutions to

ax +by = c
dx +ey = f

are ...

∆ = bd -ea
x = (bf -ec)/∆
y = (cd -fa)/∆

Using that rule here, we find ...

∆ = 5·3 -6·2 = 3

a = (5·54 -6·41)/3 = 5·18 -2·41 = 90 -82 = 8

s = (41·3 -54·2)/3 = 41 -18·2 = 5

This math can be performed in your head, which is the intent of formulating the rule in this way.

Similarly, if you expect the solutions to be small integers (as here), then graphing is another viable solution method.
