Answer:
Step-by-step explanation:
The null hypothesis
The alternative hypothesis
At 0.02 level of significance,
the testing firm rejects the null hypothesis.
This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.
Using the probability concept, it is found that:
- a) P(star) = 3/8 = 0.375 = 37.5%.
- b) P(not diamond) = 7/8 = 0.875 = 87.5%.
- c) P(flower) = 1/4 = 0.25 = 25%.
- d) You would expect to spin a heart 25 times.
------------------------------------------------
- A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
- Of the 8 sections, 3 are stars.
Then:
P(star) = 3/8 = 0.375 = 37.5%.
Item b:
- Of the 8 sections, 7 are not diamonds.
Then:
P(not diamond) = 7/8 = 0.875 = 87.5%.
Item c:
- Of the 8 sections, 2 are flowers.
Then:
P(flower) = 1/4 = 0.25 = 25%.
Item d:
- 2 out of the 8 sections are hearts, then:
Out of 100:
You would expect to spin a heart 25 times.

Answer:
6 or
feet per inch
Step-by-step explanation:
Yeah. This is a question about scaling.
Basically, it's asking how many feet (in real life) are being represented by one inch in the blueprint.
You solve it by dividing the height of the actual house by the height of the blueprint. And, since the actual house is in feet, and the blueprint is in inches, your answer will be in feet per inches.
Does that help?
