Hard networking major

Design a network for a private school that serves the learning side and allows for easier communication between teachers and students and saves time.

The mean population IQ is 100 with a standard deviation of 15. A principal at a certain school claims that the mean IQ score of their students in his school is greater that 100. A random sample of 30 students IQ scores have a mean score of 112. Significance level α = 0.01

(a) State the null and alternate hypotheses

(b) Calculate the z statistic value 6

(c) Determine the p value. Sketch the graph

(d) Make a decision. Reject or fail to reject H0 ?

(e) Is there sufficient evidence at the 1% significance level to support the principal’s claim? Explain your answer in relation to this context.

For students who first enrolled in two year public institutions in a recent​ semester, the proportion who earned a​ bachelor's degree within six years was

The president of a certain college believes that the proportion of students who enroll in her institution have a

Several years​ ago, 41​% of parents who had children in grades​ K-12 were satisfied with the quality of education the students receive. A recent poll asked 1 comma 205 parents who have children in grades​ K-12 if they were satisfied with the quality of education the students receive. Of the 1 comma 205 ​surveyed, 486 indicated that they were satisfied. Construct a 95​% confidence interval to assess whether this represents evidence that​ parents' attitudes toward the quality of education have changed.Use technology to find the 95​% confidence interval. The lower bound is _____. The upper bound is ____

A)In our sample of 204 students, 27 have September birthdays. Calculate a 90% confidence interval for the proportion of 332 students that have a September birthday.

B) Interpret the interval from part b.

C) If the birth months are equally likely (ignoring the difference in the number of days), what proportion of births would be in September?

D) For various reasons, September is considered to be the most common birth month. Using your confidence interval from part A and response from part B, explain if there is evidence to support that the proportion of September birthdays is greater than we would expect by chance.

A STAT 200 instructor wants to know if more than half of online students use the eTextbook.  Conduct a randomization test given that 80 students in a random sample of 120 use the eTextbook.

A. Determine what type of test you need to conduct and write the hypotheses.

B. Construct a randomization distribution under the assumption that the null hypothesis is true. Take at least 5000 resamples.

C. Use the randomization distribution to find the p-value.

D. Decide if you should reject or fail to reject the null hypothesis.

E. State a real-world conclusion in relation to the original research question.

In an essay of 500-750 words, explain: 1.How you would intervene and de-escalate the student with autism. 2.How you would intervene and debrief the other students in the class after a meltdown. 3.Proactive ways to prevent outbursts in the future. 4.How you would collaborate with a co-teacher to seek a solution for the situation. 5.What support you and your co-teacher might need to engage and support all students. 6.Ethical and legal concerns with sharing information with the class and other professionals. Support your findings with a minimum of two scholarly resources.
