Answer:

Test statistic = -2.44

There is enough evidence to support the strategist's claim.

Step-by-step explanation:

H0 : p = 0.41

H1 : p < 0.41

pˆ = 0.38

Test statistic :

z=pˆ−p/√p(1−p)/n

Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600

Z = - 0.03 / √0.0001511875

Z = - 0.03 / 0.0122958

Z = - 2.4399

Test statistic = -2.44

The Pvalue :

P(Z < -2.44) = 0.0073436

α - level = 0.02

If Pvalue < α ; Reject H0

0.0073436 < 0.02 ; We reject H0

Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.

Alborosie

Answer:

yes they both are wrong

Step-by-step explanation:

Center of the Circle is (h,I) which is (4,-3)

so h= 4 and k = -3

radius is 4 units (3+1)

Equation for circle

$(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2}$

substitute all the values in this equation

$(x - 4) { }^{2} + (y - ( - 3)) {}^{2} = 4 {}^{2} \\ (x - 4) {}^{2} + (y + 3) {}^{2} = 16$
