Answer:
0.75°C
Step-by-step explanation:
Person A Person B Person C
-3 4 8
-1 -4 -2
0 2 5
2 -3 1
To get Fatima mean value, we have to add all the given values together
= - 3 + 4 + 8 - 1 - 4 - 2 + 0 + 2 + 5 + 2 - 3 + 1
= 9
Estimate is 9 deg above Actual Temperature in 12 readings
The formula for our Mean Value will be, the added values divided by actual temperatures
Added values = 9
Actual temperature = 12
Mean value = 9 ÷ 12 = 0.75°C above actual Temperature
Answer:
3 hours 20 minutes
Step-by-step explanation:
Together, the workers can assemble 9 + 6 = 15 products per hour. So the assembly of 50 products will take ...
(50 products)/(15 products/hour) = 50/15 hours = 3 1/3 hours
The two workers can assemble 50 products in 3 1/3 hours.
Answer:
A) According to the regression equation, regardless of whether or not smoking is allowed in bars, the number of cigarette packs sold per 1000 people decreases by approximately 1424 for each additional dollar of cigarette tax.
Step-by-step explanation:
Given the regression equation:
PACKS i= 57221.431732 − 1423.696906TAXi + 155.441784BARSi + eᵢ.
BARS i= 1 if city i allows smoking in bars
BARSi = 0 if city i does not allow smoking in bars
R2 = 0.351292
P-value = 0.086529
Conlusion:
Simnce p value, 0.0865 is greater than level of significance, 0.05, BARS is not significant. Thus, allowing smoking in bars increase cigarette sales, since the coefficient of BARS is positive.
Correct answer is option A.
According to the regression equation, regardless of whether or not smoking is allowed in bars, the number of cigarette packs sold per 1000 people decreases by approximately 1424 for each additional dollar of cigarette tax.
