Answer:

(4.449, 0.449) and (-0.449, -4.449)

Step-by-step explanation:

xy = 2

y = \frac{2}{x}

Vertical asymptote → x = 0

Horizontal asymptote → y = 0

Input-output values for the equation,

x          -2         -1            1           2           4

y          -1         -2            2          1          0.5

Input-output values of the equation,

x - y = 4

x         -2          -1            0            1            2

y         -6          -5          -4           -3          -2

Solutions of the system of equations → (4.449, 0.449) and (-0.449, -4.449)

sergij07 [2.7K]

Answer:

There is evidence to show that  the single-earner couples on average spend more time watching television together

Step-by-step explanation:

Given that a recent study compared the time spent together by single- and dual-earner couples. According to the records kept by the wives during the study, the mean amount of time spent together watching television among the single-earner couples was 61 minutes per day, with a standard deviation of 15.5 minutes. For the dual-earner couples, the mean number of minutes spent watching television was 48.4 minutes, with a standard deviation of 18.1 minutes.

H_0: \bar x=\bar y\\H_a: \bar x > \bar y

(Right tailed test where x stands for single earner and y for double)

Let us assume sample sizes are 500 each.

Difference -12.600

Standard error 1.066

95% CI -14.6913 to -10.5087

t-statistic  -11.823

DF  998

Significance level P < 0.0001

Since p is less than alpha we reject null hypothesis.

There is evidence to show that  the single-earner couples on average spend more time watching television together
