Afood safety guideline is that the mercury in fish should be below 1 part per million (ppm). listed below are the amounts of mercury (ppm) found in tuna sushi sampled at different stores in a major city. construct a 90%confidence interval estimate of the mean amount of mercury in the population. does it appear that there is too much mercury in tuna sushi?
0.56  0.72  0.10  0.99  1.32  0.52   0.93
what is the confidence interval estimate of the population mean mu?

Explanation:

Given that:

The sample size , n = 7

The mean of the observation:

Mean = Sum of observation / Total number of observation

          = (0.56+ 0.72+ 0.10 + 0.99 + 1.32 + 0.52 + 0.93) /  7 = 0.7343

The standard deviation:

Calculating SD as:

SD = 0.3928

Degree of freedom = n-1 = 6

The critical value for t at 2% level of significance and 6 degree of freedom is  2.043.

So,

So, applying values , we get:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
