A large box contains 10,000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm, and the standard

ser-zykov [4K]

Answer:

Option a) A 95% confidence interval for the mean diameter of the 120 bearings in the sample is $10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$ .

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 120

Sample mean = 10 mm

Standard Deviation = 0.24 mm

Formula:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$

Hence, the correct interpretation for the confidence interval is given by option a).

A 95% confidence interval for the mean diameter of the 120 bearings in the sample is $10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$ .

We have to consider the factor of sampling of 120 ball bearings from a population of 10,000 ball bearings.

Five times the sum of number and 27 is greater than or equal to six times the sum of that number and 26. What is the

raketka [301]

Answer:

$x \geq -21$

Step-by-step explanation:

Let the number be x.

Translating the word problem into an algebraic equation, we have;

$5(x + 27) \geq 6(x + 26)$

Opening the bracket, we have;

$5x + 135 \geq 6x + 156$

Collecting like terms, we have;

$6x - 5x \geq 135 - 156$

$x \geq -21$
