Is the null hypothesis rejected or not rejected for an observed p-value of at 0.07 at a significance level of 0.05? Group of ans
Alex787 [66]

Answer: B) Do not reject null hypothesis

Step-by-step explanation:

When p-value is less than the significance level then we reject the null hypothesis (H_0).

When p-value is greater than or equal to the significance level then we fail to reject the null hypothesis(H_0).

Given : P-value = 0.07

Significance level = 0.05

Clearly , 0.07> 0.05

i.e. P-value > Significance level

⇒ We fail to reject the null hypothesis.

Hence, the correct answer is : B) Do not reject null hypothesis

Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for
Hitman42 [59]

Answer:

4 small

8 large

Step-by-step explanation:

s - small mug

l - large mug

Yesterday she had 200 at start of day

at end of day 188 left, so she sold 12 mugs

(1)   s + l = 12

(2)  2.50s + 5.75l = 56.00

Solve for l in (1)

l = 12 - s

substitute in l = 12 - s into (2)

2.50s + 5.75(12-s) = 56.00

2.50s + 69.00 - 5.75s = 56.00

-3.25s + 69.00 = 56.00

-3.25s = -13.00

s = 4

to find l substitute s = 4 into (1)

4 + l = 12

l = 8

The double number line shows how many bananas are needed to make 1 loaf<br> of banana bread.
frutty [35]

Answer:

(1, 2.5)  (2, 5)  (4, 10)

Step-by-step explanation:

The first blank is 1 because that's how many loaves are made while using the equivalent point on the second number line. Then you just use that same input for the second blank (2). The second blank is just the first one multiplied by 2. For the final blank you want to multiply 4 by the unit rate of bananas: 2.5. The last blank is 10.
