prohojiy [21]

Answer: The value of test statistic is 0.696.

Step-by-step explanation:

Since we have given that

n_1=1399\\\\x_1=411\\\\p_1=\dfrac{x_1}{n_1}=\dfrac{411}{1399}=0.294

Similarly,

n_2=759, x_2=211\\\\p_2=\dfrac{x_2}{n_2}=\dfrac{211}{759}=0.278

At 0.01 level of significance.

Hypothesis are :

H_0:P_1=P_2=0.5\\\\H_a:P_1\neq P_2

So, the test statistic value would be

z=\dfrac{(p_1-p_2)-(P_1-P_2)}{\sqrt{\dfrac{P_1Q_1}{n_1}+\dfrac{P_2Q_2}{n_2}}}\\\\z=\dfrac{0.294-0.278}{\sqrt{0.5\times 0.5(\dfrac{1}{1399}+\dfrac{1}{759})}}\\\\z=\dfrac{0.016}{0.023}=0.696

Hence, the value of test statistic is 0.696.

Over 11.2 hours, the temperature changed -2.9 degrees each hour. What was the total temperature change? Enter your answer in the
Doss [256]

Answer:

Total temperature change = -32.48 degrees

Step-by-step explanation:

Over 11.2 hours, the temperature changed -2.9 degrees each hour.

Total time elapsed = 11.2 hour.

Temperature change per hour = -2.9 degrees

Total temperature change = Total time elapsed x Temperature change per hour

Total temperature change = 11.2 x -2.9 = -32.48 degrees

So temperature is reduced by 32.48 degrees in 11.2 hours.

Total temperature change = -32.48 degrees
