Why are convenience samples are not desirable?
Igoryamba

Answer:

The disadvantages: Convenience samples do not produce representative results. If you need to extrapolate to the target population, convenience samples aren't going to get you there. ... Much larger convenience samples are not more accurate than small probability samples.

A manufacturer of floor wax has developed two new brands, A and B, which she wishes to subject to homeowners' evaluation to dete
sergejj [24]

Answer:

Probability that ten or more homeowners would state a preference for either brand A or brand B = 0.302

Step-by-step explanation:

Given - A manufacturer of floor wax has developed two new brands, A and B, which she wishes to subject to homeowners’ evaluation to determine which of the two is superior. Both waxes, A and B, are applied to floor surfaces in each of 15 homes. Assume that there is actually no difference in the quality of the brands.

To find - What is the probability that ten or more homeowners would state a preference for either brand A or brand B?

Proof -

Given that,

There is actually no difference in the quality of the brands.

⇒P(A) = \frac{1}{2} = 0.5

  P(B) = \frac{1}{2} = 0.5

Now,

We know that,

Binomial distribution is equals to

B(n, x) = ⁿCₓ (p)ˣ (1 - p)ⁿ⁻ˣ

Now,

P(X(A) ≥ 10) = P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)

               = ¹⁵C₁₀ (0.5)¹⁰ (0.5)⁵ + ¹⁵C₁₁ (0.5)¹¹ (0.5)⁴ + ¹⁵C₁₂ (0.5)¹² (0.5)³ + ¹⁵C₁₃ (0.5)¹³ (0.5)² + ¹⁵C₁₄ (0.5)¹⁴ (0.5)¹ + ¹⁵C₁₅ (0.5)¹⁵ (0.5)⁰

                =  0.092 + 0.042 + 0.014 + 0.003 + 0.0005 + 0.00005

                = 0.151

⇒P(X(A) ≥ 10) = 0.151

As given Quality of both brands are same ,

So, the probability of both the brands are equal

⇒P(X(B) ≥ 10) = 0.151

Now,

Probability that ten or more homeowners would state a preference for either brand A or brand B = P(X(A) ≥ 10) + P(X(A) ≥ 10)

                                           = 0.151 + 0.151

                                           = 0.302

∴ we get

Probability that ten or more homeowners would state a preference for either brand A or brand B = 0.302
