g A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number

of times, and determines that 11 of the plates have blistered. Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances

Complete Question

A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 11 of the plates have blistered. Does this provide compelling evidence for concluding that more than 10% of plates blister under such circumstances?

A) State H_0 and H_a, (5 pts)

B) Test the hypothesis using the P-Value approach at a significance level of 4%: (15 pts)

Expert Answer

Answer:

a)H_0:p=0.10

  H_a:p>0.10

b) We fail to reject Null hypothesis

Step-by-step explanation:

From the question we are told that:

Sample size n=100

No. with blistered x=11

a)

Generally the Hypothesis given as

H_0:p=0.10

H_a:p>0.10

b)

Since p=0.10

Therefore

p'=\frac{11}{100}

p'=0.11

Test statistics

Z=\frac{p'-p}{\sqrt{p(1-p)}}

Z=\frac{0.11-0.10}{\sqrt{0.10*0.90/100}}

Z=1.33

From table

P-Value =0.092

Therefore

P-value >0.04 significance level

Hence,We cannot conclude that at 4\% significance level the proportion is greater than 10\%

We fail to reject Null hypothesis

Answer:

Okay so what we need to do is prove that they are not the same.

Step-by-step explanation:

So first we need to find out what 6*2 is which practically is 6 x 6.

Its so because the exponent 2 means you multiply that by that many times. So it would look like 6 x 6 which is different from 2 x 6.

2 x 6 is just multiplying the two different numbers together, and they are not expenentiol so that's your answer.

Hope this helped :P

Statisticians use ______ scores to divide the ______ under a curve the way people use a knife to cut pizza. Just as the pizza is
solong [7]

Answer:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

Step-by-step explanation:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

z-score:

  • A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
  • Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

  • If a z-score is 0, it tells that the data point is same as the mean.
  • Area under the normal curve is 1.
