Piaget decided that adolescents in the formal operational stage use __________, in which they start with a general theory about what produces a particular outcome and then deduce explanations for specific situations in which they see that particular outcome.

According to the information-processing approach, __________ is an understanding about the processes that underlie memory, and which emerges and improves during middle childhood.

Another name for short-term memory is

According to Piaget, the ability to take multiple aspects of a situation into account occurs when children are

For the test of whether the true mean car insurance premium for Penn State graduate students is greater than $800,  

Please note that this question consists of six parts. You may use MINITAB to double check your final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question.  Manufacturer of an electric vehicle company claims that on average battery last for 340 miles on a full charge. Recently, the company has been getting many complaints about need for charging of the vehicles in less than 340 miles. Company would like to see if the true average mileage could possibly be well short of their quoted claim. They have collected data from a random sample of 51 electric vehicles manufactured by their company. Average mileage per charge for the sampled vehicles was 330 miles with a standard deviation 25 miles per full charge. Set up the appropriate null and alternative hypotheses for testing the company’s question to address the customer complaints. Make sure to use proper notations when setting up and . Are the conditions to carry out the above stated test are satisfied? If the conditions are satisfied, explain how they were satisfied for this problem rather than simply giving a “yes” or “no” answer. Calculate the test statistic. Show your calculations. Calculate the p-value for the test. You may use MINITAB to find the numerical value of the p-value for the test. However, you MUST clearly write down the probability statement. Write the final conclusion in the context of the problem (use 5% significance level). Instead of doing the above hypothesis test, suppose the company wanted to obtain an interval estimation for the true proportion of vehicles that does not last for 340 miles from a full charge. In the sample of 51 vehicles, battery did not last for 340 miles on full charge for 38 vehicles. Obtain a 95% confidence interval for the true proportion of vehicles that does not last for 340 miles in a full-charge.

For the commuter problem above, find the mean and standard deviation using the formulas for the Binomial Distribution. Round your answer to the tenth place, if needed. Mean: [BLANK-1] Standard Deviation: [BLANK-2]

Thirty-eight percent (38%) of people living in the U.S. have type O+ blood. If 3 people living in the U.S. are selected at random, what is the probability at least one has type O+ blood? Round all answers to the nearest whole percent, as applicable. Step 1: True or False: The complement of this event is that none of the 3 have type O+ blood. [BLANK-1] Step 2: What is the probability that 1 randomly selected person does NOT have O+ blood? [BLANK-2]% Step 3: The probability that we randomly select 3 people that do NOT have O+ blood would be: [BLANK-3]% Step 4: Therefore, the probability at least one of the 3 randomly select people had O+ blook is: [BLANK-4]%

I followed all testing procedures and Honorlock requirements for this exam, including completing the room scan, remaining on camera, avoiding unauthorized resources or technology, and independently completing my work.
