Answer:
When temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
Step-by-step explanation:
Let C denotes the temperature in degree Celsius and F denotes the temperature in degree Fahrenheit.
According to the given question,
To convert to Fahrenheit we multiply the Celsius temperature by 9/5 and add 32.
Mathematically it can be written as,
For example , let us take the temperature in mexico to be 30 degrees Celsius to convert the temperature to Fahrenheit we can use this equation as ,
Put C = 30, we get
Thus, when temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
The lower bound of the 90% confidence interval for the gift basket's average shipping weight is 55.605.
Given mean weight of 57 ounces ,sample size 70 ,confidence level 90% and standard deviation of 7.1 ounces.
We have to find the lower bound of the confidence interval for the gift's basket's avrage shipping weight.
We can easily find the confidence interval and its lower bound through theformula of margin of error.
Margin of error is the difference between real values and calculated values.
Margin of error=z*σ/
where z is the critical value of confidence level
σ is standard deviation,
n is the sample size
We have to first find the z value for 90% confidence level which is 1.645.
Margin of error=1.645*7.1/
=11.6795/8.3666
=1.395
Lower bound of the confidence interval = Mean - margin of error
=57-1.395
=55.605.
Hence the lower bound of the confidence interval for the gift basket's average shipping weight is 55.605.
