Two computer users were discussing tablet computers. A higher proportion of people ages 16 to 29 use tablets than the proportion of people age 30 and older. The table below details the number of tablet owners for each age group. Test at the 1% level of significance. (For subscripts let 1 = 16-29 year old users, and 2 = 30 years old and older users.)

16–29 year olds 30 years old and older

A computer company shipped two new computers to a customer. These two computers were randomly selected from the 15 computers in stock. Unfortunately, the inventory clerk by mistake mixed up new computers with refurbished computers. As a result, the 15 computers in stock consisted of 11 new computers and 4 refurbished computers. If the customer received one refurbished computer, the company will incur a shipping and handling expense of $100 to replace that computer with a new computer. However, if...

a random sample of n1= 156 people ages 16 to 19 were taken from the island of oahu, hawaii, and 16 were found to be high school dropouts. Another random sample of n2=129 people ages 16 to 19 werr taken from sweetwater county, Wyoming, and 10 were found to be high school dropouts. Do these data indicate that the population proportion of high school dropouts on Oahu is different ( either way) from that of sweetwater county? use a 1%...

A report stated that 29% of the people in a representative sample of adult Americans ages 33 to 49 rated a landline telephone among the three most important services that they purchase for their home. In a representative sample of adult Americans ages 50 to 68, 44% rated a landline telephone as one of the top three services they purchase for their home. Suppose that the samples were independently selected and that the sample size was 590 for the 33...

Suppose that in the certain country the proportion of people with red hair is 29%. Find the following probabilities if 37 people are randomly selected from the populattion of this country. Round all probabilities to four decimals. (a) The probability that exactly 6 of the people have red hair (b) The probability that at least 6 of the people have red hair (c) Out of the sample of 37 people, it would be unusual to have more than people with...

A computer manufacturer produces three types of computers: laptop, desktop, and tablet The manufacturer has designed their supply chain in such a way so that the final assembly of their computers entails putting together different quantities of the same parts. We will assume that the costs for parts unique to the model have already been accounted for in the reported per-unit profits, and that inventory levels for these other parts do not change the optimal allocation. We assume that there...

About 90% of young adult Internet users (ages 18 to 29) use social-networking sites. (a) Suppose a sample survey contacts an SRS of 1400 young adult Internet users and calculates the proportion pˆp^ in this sample who use social-networking sites. What is the approximate distribution of pˆp^? μpˆμp^ (±±0.00001) = , σpˆσp^ (±±0.00001) = What is the probability that pˆp^ is between 87% and 93%? This is the probability that pˆp^ estimates pp within 3%. (Use software.) P(0.87<pˆ<0.93)P(0.87<p^<0.93) (±±0.0001) =...
