Umnica [9.8K]

Sample mean : \overline{x}=10.6x=10.6

Standard deviation : s=1.7s=1.7

Significance level : \alpha:1-0.95=0.05α:1−0.95=0.05

Critical value : z_{\alpha/2}=1.96

Hence the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)(10.1989, 11.0011)

Of those women who are diagnosed to have early-stage breast cancer, one-third eventually die of the disease. Suppose a screening
Finger [1]

Answer:

A) Alternative hypothesis; Ha: p_o > ⅔

B) Null hypothesis;

H0: p_o = ⅔

C) There is sufficient evidence to support the claim that the community screening programme was effective

D) p-value = 0

Its less than the significance value and so we will reject the null hypothesis and conclude that the community screening programme was effective

Step-by-step explanation:

A) We are told that ⅓ of those diagnosed eventually die of the disease. Thus, ⅔ is the fraction that will survive the disease.

Thus, the null hypothesis is;

H0: p_o = ⅔

We are told that a screening programme was started to increase the survival rate. Thus,the alternative hypothesis is;

Ha: p_o > ⅔

B) null hypothesis is;

H0: p_o = ⅔

C) 164 out of the 200 women selected survived the disease.

Thus sample proportion is;

p^ = 164/200

p^ = 0.82

For the z-score value, we will use the formula;

z = (p^ - p_o)/√((p_o(1 - p_o)/n)

Now, p_o = ⅔ = 0.67

Thus;

z = (0.82 - 0.67)/√((0.67(1 - 0.67)/200)

z = 4.51

From online p-value from z-score calculator, we have p-value ≈ 0

This is less than the significant level of 0.05 and therefore we will reject the null hypothesis and conclude that the community screening program was effective.

D) p-value ≈ 0

Reject the null hypothesis

The quotient of (x4 â€"" 3x2 4x â€"" 3) and a polynomial is (x2 x â€"" 3). What is the polynomial? x4 â€"" 2x2 5x â€"" 6 x2 â€""
Sever21 [200]

The quotient of polynomials is the division of the polynomials

The polynomial is x^6 + x^5 -6x^4 +x^3 +10x^2-15x +9

Represent the polynomial with P.

So, the quotient is represented as:

\frac P{x^4 -3x^2 + 4x - 3} = x^2 + x -3

Make P the subject

P = (x^4 -3x^2 + 4x - 3)( x^2 + x -3)

Expand the expression on the right-hand side of the equation

P =x^4(x^2 + x -3) -3x^2(x^2 + x -3) + 4x(x^2 + x -3) - 3(x^2 + x -3)

Further, expand

P =x^6 + x^5 -3x^4 -3x^4 - 3x^3 +9x^2 + 4x^3 + 4x^2 -12x - 3x^2 - 3x +9

Collect like terms

P =x^6 + x^5 -3x^4 -3x^4 - 3x^3+ 4x^3 +9x^2  + 4x^2  - 3x^2-12x - 3x +9

Evaluate like terms

P =x^6 + x^5 -6x^4 +x^3 +10x^2-15x +9

Hence, the polynomial is x^6 + x^5 -6x^4 +x^3 +10x^2-15x +9
