Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value u

Alenkasestr [34]

Answer:

The value is $1.75 \ and \ -1.75$

Step-by-step explanation:

From the question we are told that

The null hypothesis is $H_1 : \mu \ne 3.24$

The level of significance is $\alpha = 0.08$

From the z table the critical value of $\alpha$ considering the two tails of the normal curve( This is because this a two tailed test ) is

$z= \pm 1.75$

Hence the critical value is

$1.75 \ and \ -1.75$

WILL GIVE BRAINLIEST!

Radda [10]

Answer:

4 ounces of corn and 4 ounces of squash

Step-by-step explanation:

Let S be the no. of ounces of squash

Let C be the no. of ounces of corn

C》2 --> (A)

S》C --> (B)

Total protein 》 3

½C + ¼S》3 --> (C)

Solve A and C simultaneously

½(2) + ¼S = 3

¼S = 2

S = 8

C = 2, S = 8

Solve B and C simultaneously

½S + ¼S = 3

¾S = 3

S = 4

C = 4, S = 4

Three possible extreme combinations

C = 2, S = 8: Total = 10

C = 4, S = 4: Total = 8

Minimum is 8 ounces

The gable end of the roof shown is divided in half by a vertical brace. Find the distance h (in ft) from an eave to the peak. 41

nlexa [21]

Answer:

h = 9 ft

Step-by-step explanation:

Assume the diagram is like the one below.

∆ABD is a right triangle.

We can use Pythagoras' Theorem to find the height h.

$\begin{array}{rcl}h^{2} + 40^{2} & = & 41^{2}\\h^{2} + 1600 & = & 1681\\h^{2} & = & 1681 - 1600\\& = &81\\h& = & \sqrt{81}\\&=& \mathbf{9}\end{array}\\\text{The height of the gable is $\large \boxed{\textbf{9 ft}}$}$
