Step-by-step explanation:
<u>Answer with explanation:</u>
As per given , we have
A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72.
i.e. n= 50
Degree of freedom = n-1=49


The point estimate of the population mean is equals to the sample mean.
i.e. The best estimate for the length of gribbles= 3.1 mm
Also, population standard deviation is unknown , then the confidence interval would be :

For df= 49 and significance level of 0.05 , the t- value (using t-distribution table) would be :

Now, Margin of error : 

95% confidence interval : 

Answer:
52.07
Step-by-step explanation:
sin of an angle is the opposite side over the hypotenuse
sin 51 = x/67
Multiply each side by 67
67 sin 51 = x
52.06877942 =x
Rounding to the nearest hundredth
52.07 =x
