Answer:

H0 : P ≤ 0.12

H1 : P > 0.12

Step-by-step explanation:

12% = 12/ 100 = 0.12

Given the population proportion, P = 0.12

The claim is the alternative hypothesis, H1 ; which is to test if more than 12% of trees have been infested.

Hence, the alternative hypothesis will be ;

H1 : P > 0.12

The null hypothesis which is the initial truth is always the opposite of the alternative hypothesis, Therefore, we write our null as ;

The null hypothesis ; H0 : P ≤ 0.12

Therefore, we have :

H0 : P ≤ 0.12

H1 : P > 0.12

dsp73

Answer:

B - 12,111

C - 11,589

Step-by-step explanation:

Here are the options

A - 10, 999

B - 12,111

C - 11,589

In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit

Rounding off 10,999 to the nearest thousand is 11,000

the hundred figure is greater than 5, so one is added to the thousand figure. The

Rounding off 12,111 to the nearest thousand is 12,000

the hundred figure is less than 5, so zero is added to the thousand figure.

Rounding off 11,589 to the nearest thousand is 12,000

the hundred figure is equal to 5, so one is added to the thousand figure.

oksano4ka [1.4K]

Answer:

80

Step-by-step explanation:

So if 50 tablets are made and 2 are defective then it’s 50:2. That means for every 50 tablets are made 2 are defective. And since 50 goes into 2000 40 times, you would multiply 40 x 2 to get 80, the number defective tablets
