Alocal company wants to evaluate their quality of service by surveying their customers. their budget limits the number of surveys to 100. what is their maximum error of the estimated mean quality for a 95% level of confidence and an estimated standard deviation of 5? 1.8130 1.1550 1.2824 1.3160

0.98

Step-by-step explanation:

Formula to find the maximum error of the mean is given by :-

, where n= sample size.

z*= Critical value.

= Population standard deviation

As per given , we have

n= 100

Confidence level : 95%

Critical value for 95% confidence = 1.96    [By z-table ]

Then , the  maximum error of the estimated mean quality will be :

Hence, the required maximum error = 0.98

Thus the correct answer is 0.98 .

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

i think it would be 42cm
