A nutrition laboratory tested 25 "reduced sodium" hotdogs of a certain brand, finding that the mean sodium content is 310 mg with a standard deviation of 36 mg. Construct a 95% confidence interval for the mean sodium content of this brand of hot dog and interpret a 95% level of confidence. Show all work

The  95% confidence interval is  

A   95% level of confidence mean that there is 95%  chance  that the true population mean will be in this interval

Step-by-step explanation:

From the question we are told that

    The sample size is  

    The mean is  

     The standard deviation is  

Given that the confidence level is  95% then the level of significance is mathematically represented as

=>        

=>        

Next we obtain the critical value of   from the normal distribution table , the value is  

Generally the margin of error is mathematically represented as

substituting values

The 95% level of confidence interval  is mathematically represented as

substituting values

The  95% level of confidence mean that there is 95%  chance  that the true population mean will be in this interval

da freeck kinda math is this just drop out

step-by-step explanation:

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
