From the information, it would be a good idea to rotate the candidate choices A. Yes, to avoid response bias.

<h3>Response bias</h3>

From the complete question, it should be noted that a good idea to rotate the candidate choices in order to avoid response bias.

When conducting any survey that has multiple choices, the respondents have a tendency to quickly finish up the survey by answering the survey questions quickly.

In this process, this can lead to bias towards the first and last choice. Since the sample of 20 registered voters was surveyed, it is wise to rotate the candidate choices.

This question is Incomplete

Complete Question

Researchers recorded the speed of ants on trails in their natural environments. The ants studied, Leptogenys processionalis, all have the same body size in their adult phase, which made it easy to measure speeds in units of body lengths per second (bl/s). The researchers found that, when traffic is light and not congested, ant speeds vary roughly Normally, with mean 6.20 bl/s and standard deviation 1.58 bl/s. (a) What is the probability that an ant's speed in light traffic is faster than 5 bl/s? You may find Table B useful. (Enter your answer rounded to four decimal places.)

Answer:

0.7762

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Population mean = 6.20 bl/s

Standard deviation = 1.58 bl/s.

x = 5 bl/s

z = 5 - 6.20/1.58

z = -0.75949

The probability that an ant's speed in light traffic is faster than 5 bl/s is P( x > 5)

Probability value from Z-Table:

P(x<5) = 0.22378

P(x>5) = 1 - P(x<5)

= 1 - 22378

= 0.77622

Approximately to 4 decimal places = 0.7762

The probability that an ant's speed in light traffic is faster than 5 bl/s is 0.7762

Plzzzzzzzz. Helpppp hurryyyyyy I got more thanks

21)

Answer : 2x + 3 (Option D)

When x = 1, 2(1) + 3 = 5
When x = 2, 2(2) + 3 = 7
When x = 3, 2(3) + 3 = 9
When x = 4, 2(4) + 3 = 11

Question 22)

The square of y decreased by the quotient of 28 and 7.

Quotient of 28 and 7 = 28/7

Decreased by square of y = -y²

Therefore the expression is 28/7 - y² (Option A)
