Eduardwww [97]

Answer:

(A)  H_0 : μ = 22 ; H_A : μ ≠ 22

(B) Value of the test statistic = -2.69

Step-by-step explanation:

We are given that a local bottler in Hawaii wishes to ensure that an average of 22 ounces of passion fruit juice is used to fill each bottle. He takes a random sample of 65 bottles. The mean weight of the passion fruit juice in the sample is 21.54 ounces. Assume that the population standard deviation is 1.38 ounce.

We have to test the accuracy of the bottling process.

(A) Let, NULL HYPOTHESIS, H_0 : \mu = 22 ounces  {means that an average of 22 ounces of passion fruit juice is used to fill each bottle}

ALTERNATE HYPOTHESIS, H_A : \mu \neq 22 ounces  {means that an average of 22 ounces of passion fruit juice is used to fill each bottle}

The test statistics that will be used here is One-sample z-test;

             T.S. = \frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } } ~ N(0,1)

where, \bar X = sample mean weight of the passion fruit juice = 21.54 ounces

            \sigma = population standard deviation = 1.38 ounces

            n = sample of bottles = 65

(B) So, <u>test statistics</u> =  \frac{21.54-22}{\frac{1.38}{\sqrt{65} } }

                                  = -2.69

Hence, the value of test statistics is -2.69.

What are the solution(s) of x2-4-0?<br> X= 4 or X=4<br> X=-2 or x= 2<br> x=2<br> x=4
Pavel [41]

Answer:

Step-by-step explanation:

First you add 4 on both sides

X^2=0

Then you take square on both sides

X=+- the square root of 4

Simplify that

X=plus or minus 2

The answer can be either -2 or +2 (which is just 2)

240w times 18y

you always use the last numbers and that would equal...

____________________________________________________________

66x times 4320y=

285120 divide it by 6= 47520

then by 12

47520 divided by 12=

3960-80= 3880

3880 divided by 16 times 4

your answer is 970y
