A random sample of 330 electronic components manufactured by a certain process are tested, and 30 are found to be defective. A d
avanturin [10]

Answer:

The result is significant.

Step-by-step explanation:

Here,

p = 30 ÷ 330 = 0.091

thus, q = 1 - p = 0.909

Also, \sigma=\sqrt{\frac{pq}{n} }

⇒ \sigma=\sqrt{\frac{0.091\times0.909}{330} }=0.0158

The z-score is:

z=\frac{p-p_{0}}{\sigma}

z=\frac{0.091-0.05}{0.0158}=2.595

Thus, at 95% confidence interval, p-value = 0.005

The result is significant at p < .05.

Calculate mpg for w=1000,w=2000;calculate weight when mpg=30
Setler79 [48]

Based on the information above, the car with 1,000 pounds more will only go 1,194 miles, and the one with 2,000 pounds more will only go 1,188 miles.

<h3>What does MPG stand for?</h3>

MPG stands for miles per gallon, and refers to the distance in miles a vehicle travels for each gallon of fuel in its tank.

In general, a car consumes about 1,200 miles per gallon. However, when you add load to it, its fuel consumption is higher because it requires more force to move.

Additionally, some studies state that for every 1,000 pounds of weight added to the car, it will yield 0.5% less. So if the car has 1,000 more pounds, it's not going to go 1,200 miles per gallon, it's going to go 1,194 miles.

On the other hand, if 2,000 pounds of weight were added, the fuel economy would be 1% less, that is, it would travel 1,188 miles per gallon.
