A consumer electronics firm has developed a new type of remote control button that is designed to operate longer before becoming

intermittent. A random sample of 35 of the new buttons is selected and each is tested in continuous operation until becoming intermittent. The resulting lifetimes are found to have a sample mean of = 1,241.2 hours and a sample standard deviation of s = 110.8. Assuming normality of the population, the p-value for testing H0 versus Ha can be calculated to be .0174. (a) Determine whether H0 would be rejected at each of α = .10, α = .05, α = .01, and α = .001.

Answer:

At 0.10 significance level, reject H0

At 0.05 significance level, reject H0

At 0.01 significance level, fail to reject H0

At 0.001 significance level, fail to reject H0

Step-by-step explanation:

The null hypothesis is rejected if the p-value is less than or equal to the significance level.

Fail to reject the null hypothesis if the p-value is greater than the significance level.

At 0.1 and 0.05 significance level, the null hypothesis is rejected because the p-value (0.0174) is less than the significance levels.

At 0.01 and 0.001 significance level, fail to reject the null hypothesis because the p-value (0.0174) is greater than the significance levels.

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3
Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

  • EFJL is dilation of ABIK
  • AB has a length of 12
  • EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25
