Mixed number: 2 3/4
improper fraction: 11/4
1 17/20
the 1 is ur whole number....it stays ur whole number
17/20 = 0.85
so we have 1.85.....to turn it into a percent, move the decimal 2 spaces to the right = 185%
600 ---> 250
600 - 250 = 350
350 / 5 = 70
Average decrease in value per year: $70
Answer:
a
The 95% confidence interval is 
b
Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States
Step-by-step explanation:
From the question we are told that
The population mean is 
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 95% then the level of significance is mathematically represented as

=> 
=> 
The critical value for
obtained from the normal distribution table is

Generally the margin of error is mathematically represented as

=> 
=> 
Generally the 95% confidence interval is mathematically represented as

=> 
=> 
Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States
Answer:
e
Step-by-step explanation:
<u><em>I think your full question is below: </em></u>
<em>A store asked 250 of its customers whether they were satisfied with the service or not. The responses were also classified according to the gender of the customers. We want to study whether there is a relationship between satisfaction and gender.
</em>
<em>A meaningful display of the data from this study would be:
</em>
<em>(a) side-by-side boxplots
</em>
<em>(b) a pie chart
</em>
<em>(c) a histogram
</em>
<em>(d) a scatterplot
</em>
<em>(e) a two-way table</em>
Explain: two-way frequency table will deal with two variables, between two sets of categorical data. With genders we have two types: man and female, so two - way table are the best option to display your data.
