The minimum score needed to make an A is 89.

<h3>What is the z-score?</h3>

A Z Score, also known as the Standard Score, is a calculation used to determine how many standard deviations a raw score is below or above the population mean. Simply said, the Z Score informs you of a value's relationship to the mean and the distance a data point is from the mean.

Since the grades of his students were normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = grades of his students.

µ = mean grade

σ = standard deviation

From the information given,

µ = 74

σ = 10

The professor has informed us that 6.3 percent of his students received A's. The p-value for the minimum score is 1 - 0.063 = 0.937. The z value of 0.937 is 1.53.

1.53 = (x - 74)/10

1.53 × 10 = x - 74

15.3 = x - 74

x = 15.3 + 74

x = 89.3

Therefore, the minimum score needed to make an A is 89.

The complete question is given below:-

A professor at a local community college noted that the grades of his students were normally distributed with a mean of 74 and a standard deviation of 10. The professor has informed us that 6.3 percent of his students received A's while only 2.5 percent of his students failed the course and received F's. What is the minimum score needed to make an A?

Firlakuza [10]

Answer:

Option (D) is the right answer.

Explanation:

DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.

According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.

Hence option (D) is the most appropriate answer.

While other options are wrong because of the following reasons:

  • Static IP is the type of IP address which is fix and doesn't change in the system after rebooting, hence it has no connection in the change of IP address.
  • If the DHCP server is working well there is no chance of interference from the surrounding device.
  • Network setting has no connection with computer power supply as SMPS is used to give power and boot system only.
