NPTEL Data Analytics With Python Assignment 5 Answers 2022:- All the Answers provided below to help the students as a reference, You must submit your assignment at your own knowledge.

## What is Data Analytics with Python?

Data Analytics with Python is a fun-filled whirlwind tour of 30 hrs, covering everything you need to know to fall in love with the most sought-after skill of the 21st century. This course includes examples of analytics in a wide variety of industries, and we hope that students will learn how you can use analytics in their careers and life. One of the most important aspects of this course is that you, the student, are getting hands-on experience creating analytics models we, the course team, urge you to participate in the discussion forums and to use all the tools available to you while you are in the course

## CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of the average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

## NPTEL Data Analytics with Python Assignment 5 Answers 2022:-

Q1. In the analysis of variance procedure (ANOVA) the term “factor” refers to:

1. the dependent variable
2. the independent variable
3. different levels of a treatment
4. the critical value of F

Q2. In a problem of ANOVA, involving 3 treatments and 10 observations per treatment, SSE = 500. The MSE for this situation is:

1. 130.2
2. 48.8
3. 18.52
4. 30.0

Q3. The ‘F’ ratio in a completely randomized ANOVA is the ratio of

1. MST/MSE
2. MSTR/MSE
3. MSE/MSTR
4. MSE/MST

Q4. An ANOVA procedure is applied to data obtained from 7 samples where each sample contains 10 observations. The degrees of freedom for the critical value of F are:

1. 7 numerator and 20 denominator degrees of freedom
2. 5 numerator and 20 denominator degrees of freedom
3. 6 numerator and 63 denominator degrees of freedom
4. 7 numerator and 63 denominator degrees of freedom

Answer:- 3. 6 numerator and 63 denominator degrees of freedom

Q5. In an ANOVA problem if SST = 200 and SSTR = 80, then SSE is

1. 280
2. 120
3. 80
4. 220

Q6. The critical F value with 8 numerator and 29 denominator degrees of freedom at alpha = 0.01 is

1. 2.18
2. 3.20
3. 3.53
4. 3.94

Q7. Two Independent simple random samples are taken to test the difference between the means of two populations. The standard deviations are not known, but are assumed to be equal. The sample sizes are n1 = 15 and n2 = 35. The correct distribution to use is the:

1. t distribution with 51 degrees of freedom
2. z distribution with 50 degrees of freedom
3. z distribution with 49 degrees of freedom
4. t distribution with 48 degrees of freedom

Answer:- 4. t distribution with 48 degrees of freedom

Q8. Stare true or false:

Statement: The sampling distribution of two populations P bar1 -P bar2   is approximated by a normal distribution

1. True
2. False

Q9. Mean marks obtained by male and female students of school ABCD in first unit test are shown as below.

Male Female

Sample Size 64 36

Sample Mean Marks 44 41

Population Variance 128 72

The standard error for the difference between the two means is

1. 4.0
2. 7.46
3. 4.24
4. 2.0

Q10. Mean marks obtained by male and female students of school ABCD in first unit test are shown as below.

Male Female

Sample Size 64 36

Sample Mean Marks 44 41

Population Variance 128 72

If you are interested in testing whether or not the average marks of males is significantly greater than that of females, the test statistic is:

1. 2.0
2. 1.5
3. 1.96
4. 1.645
