Answer:
The probability that a randomly selected consumer will recognize Amazon is 0.988.
Step-by-step explanation:
The data given in the question is
Total number of consumers = 795 + 10 = 805
Consumers who knew of Amazon = 795
Consumers who did not know of Amazon = 10
The formula for calculating probability of an event A is:
P(A) = No. of favourable outcomes/Total no. of possible outcomes
P(Recognize Amazon) = No. of Consumers who knew Amazon/Total no. of consumers
P(Recognize Amazon) = 795/805
= 0.98757
P(Recognize Amazon) ≅ 0.988
The probability that a randomly selected consumer will recognize Amazon is 0.988.
Answer:
Step-by-step explanation:
To find the diagonal, use Pythagorean theorem,
diagonal² = side² + side²
= (9√3)² + (9√3)²
= 9²(√3)² + 9²(√3)²
= 81*3 + 81*3
= 243 + 243
= 486
diagonal = √486 = 22.05 units
Answer:
A. The lowercase symbol, p, represents the probability of getting a test statistic at least as extreme as the one representing sample data and is needed to test the claim.
Step-by-step explanation:
The conditions required for testing of a claim about a population proportion using a formal method of hypothesis testing are:
1) The sample observations are a simple random sample.
2) The conditions for a binomial distribution are satisfied
3) The conditions np5 and nq5 are both satisfied. i.e n: p≥ 5and q≥ 5
These conditions are given in th options b,c and d.
Option A is not a condition for testing of a claim about a population proportion using a formal method of hypothesis testing.
Look at the first line: y = (3/5)x - 3. What happens if you multiply each term by 5, to eliminate the fraction?
5y = 3x - 3
Compare this to the second equation,
5y - 3x = -10, or 5y = 3x - 10.
The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line. Since 5y = 3x is present in both equations, the two lines MUST be parallel.
y = 4
4y = 6 => y = 6/4
y+4 and y =3/2 are both horizontal lines. Since they are horiz., they are parallel.
