John’s Limited manufactures screws that are used in the manufacture of tables. The table manufacturers require that the screws m

ust have a length of 150 mm, with a small tolerance for differences in length.
Resultantly, John’s Ltd randomly sampled and measured the average length of screws for 25 production runs. Due to the fact that the table manufacturers require a small tolerance for differences in the length of the screws, a 1% significance level for evaluation was chosen.

After measuring the average of the samples and their standard deviation, it was observed that the sample values was normally distributed about the mean.
Assume John’s Ltd derived the following values from their test:

Mean = 150.12
Standard Deviation = 0.496

Requirements:
Consider the above scenario and conduct a hypothesis test using the 1% significance. In your answer, include the different steps used to construct a hypothesis test using the critical value method. See steps below.


•Null and alternative hypotheses

•Level of significance

•Test statistics

•Critical values and rejection region

•Process of checking to see whether the test statistic falls in the rejection region and conclusion in words

January 9: 80 units for $3.20

January 25: 100 units for $3.34

Ending inventory= 100*3.34 + 50*3.2= $494

Explanation:

While the days are picked at random, the size of the sample is enough to represent the reality. Among the random pick those days of football game will be picked too and will skewed to the right the distribution

The distribution will not change into normal as the reality is that distribution of revenue is not normally distributed among the days of the year.

A sample of gas occupies 575 ml at 1.50 atm and 125 degrees celsius. if temperature is changed to 20 degrees celsius and volume
Anastaziya [24]

A sample of gas occupies 575 ml at 1.50 atm and 125 degrees Celsius. If the temperature is changed to 20 degrees Celsius and the volume is changed to 0.300 L. The will be a new pressure at 2.12 atm.

Temperature is the measure of hotness or coldness expressed in phrases of any of numerous scales, including Fahrenheit and Celsius. Temperature shows the route wherein heat energy will spontaneously waft—i.e., from a hotter frame (one at a higher temperature) to a less warm body (one at a decreased temperature).

The common body temperature is ninety-eight.6 F (37 C). however normal frame temperature can vary between ninety-seven F (36.1 C) and 99 F (37.2 C) or more. Your frame temperature can range depending on how active you are or the time of day.

The heat of an item is the entire strength of all of the molecular motion interior of that item. Temperature is the degree of the thermal energy or average warmth of the molecules in a substance. SI Unit

V₁ = 0.575L

P₁ =1. So atm.

T₁ =125 + 273=398 k

√2 =0.300 L

P₂ =?

T₂ = 20 +273= 293K

P1XV 1=T2

1.50 X 0.575 lit=398 K

P2 x 0.300 lit =293K

1-50 atm x 293KX 0.575 lit

0. 300 lit X 396 K

P₂ =2.1165 atm

katovenus [111]

Answer:

Role-Based Access Control (RBAC)

Explanation:

Instead of assigning access for each user account individually, Role-Based Access Control (RBAC) is a more efficient and easier-to-manage approach.

In computer systems security, role-based access control or role-based security is an approach to restricting system access to authorized users. <u>It is used by the majority of enterprises with more than 500 employees,</u> and can implement mandatory access control or discretionary access control.

Hence, access need not be assigned for each user individually.
