calculate the total surface area of a prism that has its base 6cm and side 8 cm, the length of the prism being 50cm, find the volume of the prism​

the volume of this prism is 2400

Step-by-step explanation:

because 6x8x50=2400

Does not exceed 2% in both cases.

Step-by-step explanation:

Given that a  manufacturer of interocular lenses will qualify a new grinding machine if there is evidence that the percentage of polished lenses that contain surface defects does not exceed 2%.

Sample proportion =

Create hypothesses as

(Right tailed test at 5% significance level)

P difference = 0.004

Std error = 0.0089

test statistic Z = p diff/std error = 0.4518

p value = 0.326

Since p >alpha, we accept nullhypothesis

b) For confidence interval 97% we have

Margin of error = 2.17* std error = 0.0192

Confidence interval

=

Since 2% = 0.02 lies within this interval we accept null hypothesis.

Does not exceed 2%

Since
