a university is interested in promoting graduates of its honors program by establishing that the mean GPA of these graduates exc

shusha [124]

Answer:

Step-by-step explanation:

We would set up the hypothesis test.

For the null hypothesis,

µ ≥ 3.5

For the alternative hypothesis,

µ < 3.5

It is a left tailed test.

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 3.5

x = 3.6

σ = 0.4

n = 36

z = (3.6 - 3.5)/(0.4/√36) = 1.5

Looking at the normal distribution table, the probability corresponding to the z score is 0.933

The p value gotten is to the right of the normal curve. Since it is a left tailed test, we need the p value to the left of the curve. Therefore,

p = 1 - 0.933 = 0.067

Since alpha, 0.05 < than the p value, 0.067, then we would fail to reject the null hypothesis. Therefore, At a 5% level of significance, there is no significant evidence that mean GPA of these graduates does not exceed 3.50

numbers such as 543 or 531 have their digts in decreasing order beacuse each digit is less than the digit to its left. the digit

ycow [4]

The numbers are - 210 , 310, 320, 321, 410, 420, 421, 430, 431, 432, 543, 542, 541, 540, 532, 531, 530, 521, 520, 510

<u>Explanation:</u>

To find the number between 100 and 599 that have their digit in decreasing order, we can use combination method. The first digit cannot be 1, because there are no descending options for the following digits.

If the first digit is 2, then the only possibility is 210.

If the first is 3, the numbers can be 310, 320, and 321.

If the first is 4, they can be 432, 431, 430, 421, 420, 410

If the first is 5, they can be 543, 542, 541, 540, 532, 531, 530, 521, 520, 510

Therefore, there are 20 numbers that satisfies the rule.

The numbers are - 210 , 310, 320, 321, 410, 420, 421, 430, 431, 432, 543, 542, 541, 540, 532, 531, 530, 521, 520, 510

HELP ME THIS IS SO CONFUSING

Harrizon [31]

Answer:

365 degrees :)

Step-by-step explanation:

It's a multiple of 5, but with no zeros, so that means the ones place is 5. The hundreds place is two less than 5, so that's 3. And the tens place is two times the 3, so that gives you 365!

How do I solve this?

Minchanka [31]

The maximum happens at x = -b/2a

x = -48/2(-16) = 3/2

Now replace x in the equation and solve for y:

y = 48(3/2) - 16(3/2)^2

y = -72 - 36

y = 36

The maximum height is 36 feet.
