The manager randomly selects n 25 customers entering the restaurant, and observes how long each waits in line, in minutes, until her/his order is recelved. The waiting-times, along with a visual representation of the sample, is provided below 14,4.5, 1.3,4.5,2.9,0.4,4,3.1,7,9.3,1.7,0.2, 13.6,4.1,2,3.3,5.4, 12,20.6,3.7,2.3,6.5,4.5,2.4,7.5 Data from the sample, are saved in the Download .csv file.

Explanation / Answer

Solution:

restaurant
1 1.4
2 4.5
3 1.3
4 4.5
5 2.9
6 0.4
7 4.0
8 3.1
9 7.0
10 9.3
11 1.7
12 0.2
13 13.6
14 4.1
15 2.0
16 3.3
17 5.4
18 12.0
19 20.6
20 3.7
21 2.3
22 6.5
23 4.5
24 2.4
25 7.5

mean=5.13

median=4

there are outliers seen

From histogram it is right skewed

sd=s=4.64

coming to answerr:

a:x is numerical that is discrete

b)mean>median

skewed to right

c)mean=5.13

d)median=4

e)X,because the median is less sensitive to extreme observations

f)4.64

i hv used R to conclude.the script is

restaurant <- c(1.4,4.5,1.3,4.5,2.9,0.4,4,3.1,7,9.3,1.7,0.2,13.6,4.1,2,3.3,5.4,12,20.6,3.7,2.3,6.5,4.5,2.4,7.5)
mean(restaurant)
median(restaurant)
hist(restaurant)
boxplot(restaurant)
print(restaurant)
sd(restaurant)
shapiro.test(restaurant)
