Answer:
applying one way ANOVA:
R² = SSR / SST
= 0.133/1.807
=0.0734
Source of Variation SS df MS F P-value F0.05(2.27)
treatments 0.133 2 0.066 1.069 0.3574 3.354
error 1.675 27 0.062
Total 1.807 29
as p value is not significantly low:
Do the ANOVA results indicate that the null hypothesis (H0) can be rejected in favor of the alternative hypothesis (HA)? -No
Step-by-step explanation:
Using sampling concepts, it is found that the method that would result in a random sample is given by:
Pick 150 students' names from a jar that has the names of all the students in the school.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
Researching the problem on the internet, the representative(all possible students can possibly be sampled) and random sample is given by the following option:
Pick 150 students' names from a jar that has the names of all the students in the school.

A) is 164 because 6 times 6 is 36. 500 - 36 is 164
A. A Plus Plumbing company charges $60 per hour and $80 as a one-time fee cause 320-140/4-1 equals 180/3 equals 60 and y-140=60(x-1)
y=60x-60+140
y=60x+80
Answer:
D) II and III are both correct.
Step-by-step explanation:
The Probability distribution is the function which describes the likelihood of possible values assuming a random variable. The cost of flowers for a wedding is $698. The 95% of all samples of size is 40 and the confidence interval will be mean cost of flowers at wedding. There is confidence that mean cost of wedding flowers is between $701 to $767.
