shutvik [7]

The value of 3 in 4,385 is 1/10 times the value of 3 in 3,999.
because, value of 3 in 4,385 is 300 and value of 3 in 3,999 is 3000

Answer:

angle xyb will measure 123 degrees.

Step-by-step explanation:

because we know that angle ayz is 57 degrees and angle xyz is 90, we find that angle xya measures 33 degrees by subtracting 57 from 90. then, we can find angle xyb by subtracting 33 from 180, getting 147 degrees. when we add 147, 33, and 57, we get 237 degrees. finally, we subtract 237 from 360 and get 123 degrees, our final angle. hope this helps:)

Conduct a full hypothesis test and determine if the given claim is supported or not supported at the 0.05 significance level. A

monitta

Solution:-

- The population proportion, P = 0.03 ( 3 % )

- The sample proportion, p = 0.058 ( 5.8 % )]

- The sample size , n = 85.

- State the hypothesis:

Null hypothesis : P = 0.03 ( 3 % )

Alternate hypothesis : P ≥ 0.03 ( 3 % )

- The rejection region is defined by the significance level α:

significance α = 0.05

Z-critical = Z_α = Z_0.05

p-value = Z_0.05 = 1.645

- The Z-statistics:

$Z = \frac{\sqrt{n}*(p - P ) }{\sqrt{P*(1-P)} }\\\\Z = \frac{\sqrt{85}*(0.058 - 0.03 ) }{\sqrt{0.03*(1-0.03)} }\\\\Z = 1.5132$

- Compare against the rejection value ( p - value ):

Z-critical = 1.645

Z-test = 1.5132

Z-test < Z-critical ... ( Null not rejected )

- We fail to reject the Null hypothesis, there is not enough evidence to support the manager's claim that the production process is out of control. Hence, we can support that the production process is not out of control.
