A sample of 900 computer chips revealed that 75% of the chips do not fail in the first 1000 hours of their use. The company's pr

Vaselesa [24]

Answer:

No the evidence is not sufficient

Step-by-step explanation:

From the question we are told that

The sample size is $n = 900$

The sample proportion is $\r p = 0.75$

The population proportion is $p = 0.72$

The Null hypothesis is

$H_o : p = 0.72$

The Alternative hypothesis is

$H_a : p > 0.72$

The level of significance is given as $\alpha = 0.05$

The critical value for the level of significance is $t_{\alpha } = 1.645$

Now the test statistic is mathematically evaluated as

$t = \frac{\r p - p }{ \sqrt{\frac{p(1-p)}{\sqrt{n} } } }$

substituting values

$t = \frac{ 0.75 - 0.72 }{ \sqrt{\frac{0.72 (1-0.72)}{\sqrt{900} } } }$

$t = 0.366$

Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim

You are staffing a new department, and you have applications on your desk. You will hire 2 of the 5 software engineers who have

Makovka662 [10]

Answer:

The total number of possible complete staffs you could hire is 350.

Step-by-step explanation:

The order that the software engineers are is not important. For example, hiring John and Laura as the software engineers is the same as hiring Laura and John. The same applies for the computer engineers. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

What is the total number of possible complete staffs you could hire?

2 software engineers from a set of 5

3 computer engineers from a set of 7

$T = C_{5,2}*C_{7,3} = \frac{5!}{2!3!}*\frac{7!}{3!4!} = 10*35 = 350$

The total number of possible complete staffs you could hire is 350.
