0.002 is 1/10 of what
Yuri [45]

0.002=1/10x

Flip the equation.

1/10x=0.002

Multiply both sides by 10.

10*(1/10x)=(10)*(0.002)

x=0.02

0.002 is 1/10 of 0.02

A large software company gives job applicants a test of programming ability, and the mean for that test has been 160 in the past
Anastaziya [24]

Answer:

Since the computed value of t=  0.833 does not fall in the critical region we therefore do not reject H0 and may conclude that population mean is greater than 160. Or the sample comes from population with mean of 165.

Step-by-step explanation:

  1. State the null and alternative hypothesis as

H0: μ= 160 against the claim Ha :μ ≠160

Sample mean = x`=  165

Sample standard deviation= Sd= 12

2.  The test statistic to use is

t= x`-μ/sd/√n

which if H0 is true , has t distribution with n-1 = 36-1= 35 degrees of freedom

3. The critical region is t< t (0.025(35)= 2.0306

t= x`-μ/sd/√n

4. t = (165-160)/[12/√(36)] = 5/[6] = 0.833

5. Since the computed value of t=  0.833 does not fall in the critical region we therefore do not reject H0 and may conclude that population mean is greater than 160. Or the sample comes from population with mean of 165.

Now

6. The p-value is 0 .410326 for  t= 0.8333 with 35 degrees of freedom.
