<span>3/4 times 5. 3/4x 5/1 and it would be 15/4, which would be simplified to 3 3/4 or 3.75 lbs</span>
Each flipping is independent, and the probability of getting a head per flipping is 1/2, so the probability of getting 11 heads in a row is (1/2)^11=1/2048.
Interpret (not sure what your instructor wants, but this is how I would interpret it): when a coin is flipped 11 times, there are 2048 outcomes, only one of the outcomes is 11 heads in a row.
Answer:
The gold shipment truly is made of 75% gold, but the designer concludes that it is made of less than 75% gold. The designer will reject the shipment of gold and miss out on an honest business relationship with the supplier.
Step-by-step explanation:
Type I error is defined as the rejection of the true null hypothesis. It is also called as the 'false positive' conclusion or 'false positive' findings. The value of alpha or the significance level determines the probability of making the error type I.
In the context, it is given that for a gold piece to be of 18 karat , the piece of jewelry must be made of 75% of pure gold.
The null hypothesis is, H0: The proportion of metal that is gold is 75%
The alternative hypothesis is Ha: The proportion of metal that is gold is less than 75%.
Thus the type I error is when the gold shipment is made of 75% gold but the jewelry designer rejects the shipment thinking that the shipment is made of less than 75% gold.
Thus it shows the error of type I rejecting the null hypothesis.
