Four different paints are advertised as having the same drying time. To check the manufacturer’s claims, five samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. The following data were obtained.

Paint 1 128 | 137 | 135 | 124 | 141
Paint 2 144 | 133 | 142 | 146 | 130
Paint 3 133 | 143 | 137 | 136 | 131
Paint 4 150 | 142 |135 |140| 153

At the α = 0.05 level of significance, test to see whether the mean drying time is the same for each type of paint.

Null Hypothesis: Thers is no significance mean difference between the four different paints.

Alternative Hpothesis: There is a significance mean difference between the four different paints. ANOVA test for this by using some statistical package we have the following results one-way ANOVA

Step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
