The graduate record examination (gre) is a test required for admission to many u. s. graduate schools. students' scores on the quantitative portion of the gre follow a normal distribution. (source.

) suppose a random sample of 10 economics students took the test, and their scores are given below.

158, 166, 158, 149, 154, 164, 169, 144, 155, 160

test the claim that the mean quantitative score is greater than 152.1 at the 0.10 level of significance.

i. state your null and alternative hypothesis:
ii. describe what you type into your calculator to have it run the numbers.
iii. state your p-value
iv. state your conclusion is a way a non-stat student would understand.

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
