Okay, someone please answer, this is due today- im going to cry, nobody is willing to help me so please someone who knows answer please! ok so, there are 4 parts in this question;
part 1: 70, 62, 67, 74, 80, 82, 77, 77, 80, 80
i already gave

mean of: 74.9

median of: 77

mode of: 80

Part 2: I have a 5-summary of 67, 70, 77, 80, 80 ( dont know if its right )

in part 3, i have to sketch a box and whisker plot for the data. can someone help me on this part???

part4: i need to know Which measure of central tendency best represents the data.

-i only need part 3 and 4.-

here i attached the dot plot so u can draw on it for part 3.

please guys, my missing assignments are due tomorrow and i think i will die

draw a number line from 66 to 81

make your minimum 67

lower quartile should be on 70

the median on 77

upper quartile and maximum on 80

(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)

You can search up "box plot" and go on images to see what i mean

(copy and pasted from your last post!)

Step-by-step explanation:

I can probably help on part 4 and send a sketch but I currently can't use my phone to send a pic and I am currently on my desktop :'(

I rlly hope you do well! Don't lose hope! <3

(also like ur pfp, i enjoyed the anime too ahehe)

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
