Answer is option 4. working out attached
hope it helps :)
The whole length of the poster is 4 feet. There are three people who will paint an equal length, so this means that we need to divide the 4 feet of the poster between 3 people.
4 ÷ 3 <span>≈ 1.3
Each student will paint 1.3 feet, or 1 foot and 4 inches of the poster.</span>
Answer:
Getting a multiple of 5 is the least likely outcome.
Step-by-step explanation:
We spin a spinner that has 8 equal-sized sections numbered 1 - 8.
We have to find which is the least likely to occur.
The number is even when outcomes are 2,4,6 or 8.
Number of outcomes = 4
If the number is less than 3, the number of possible outcomes are 2 that is 1 and 2.
If the number is greater than 3 , number of possible outcomes is 5 which are 4,5,6,7 and 8.
If the number is a multiple of 5, only 1 outcome is there which is 5 itself.
Hence getting a multiple of 5 is the least likely outcome.
Answer:-4
Step-by-step explanation:
Answer:
32 days must be sampled to test the proposed hypothesis.
Step-by-step explanation:
Consider the provided information.
The average number of person-hours per day spent on these task was
.
The actual value of μ is 12 hours or less i.e μ=12
She wants a test having α=0.05
The probability of a type II error of at most β=0.10 and σ=7.64.
δ = μ-μ0
= 12-16
= -4
Now use the formula for calculating the sample size:

Substitute the respective values.



Hence, 32 days must be sampled to test the proposed hypothesis.
