Answer:
Likert Scale Question Format
Step-by-step explanation:
A Likert scale is a psychometric scale commonly involved in research that makes use of questionnaires. The Likert scale assumes that the strength of an attitude is linear, assumes that attitudes can be measured.
In addition to measuring statements of agreement, Likert scales can also be used to measure frequency, quality, importance, and likelihood, etc.
The data obtained can be summarize using a median or a mode.
The distribution of observations can also be displayed in a bar chart (it can’t be a histogram, since the data is not continuous.
Answer:
b
Step-by-step explanation:
This would definitely vary but if I were to say I would probably think each story would be about 10 feet so it so 2 stories should be about 20 feet. but keep in mind that every building is unique.
Answer:
a) 281 days.
b) 255 days
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

(a) What is the minimum pregnancy length that can be in the top 8% of pregnancy lengths?
100 - 8 = 92th percentile.
X when Z has a pvalue of 0.92. So X when Z = 1.405.




(b) What is the maximum pregnancy length that can be in the bottom 3% of pregnancy lengths?
3rd percentile.
X when Z has a pvalue of 0.03. So X when Z = -1.88
