A salesman for a new manufacturer of cellular phones claims not only that they cost the retailer less but also that the percentage of defective cellular phones found among his products, ( p1 ), will be no higher than the percentage of defectives found in a competitor's line, ( p2 ). To test this statement, the retailer took a random sample of 185 of the salesman's cellular phones and 150 of the competitor's cellular phones. The retailer found that 22 of the salesman's cellular phones and 11 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim? Use a significance level of α=0.05 for the test.
Step 1 of 6 : State the null and alternative hypotheses for the test.
Researchers conducted a prospective cohort study to assess the association between dietary supplements and cognitive ability among children. A total of 500 children age 12-17 years who take an omega-3 fatty acid supplement are compared with 500 children age 12-17 years who do not take an omega-3 fatty acid supplement. Researchers follow the children for 2 years. During this time, 300 children who take the supplement earn what is classified as a “high” score on a cognitive test while 200 children who do not take the supplement earn what is classified as a “high” score on the same cognitive test.

Such hypotensive drugs are frequently effective but are also linked to side effects like irritability and a decline in energy. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and spouses. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 patients as "improved." Meanwhile, the spouses rated 74 of the 75 patients as "worse." Why might spouses and doctors differ in their opinion about the effect of going on blood pressure medication?arrow_forwardTextbook authors must be careful that the reading level of their book is appropriate for the target audience. Some methods of assessing reading level require estimating the average word length.

Does this sample indicate that the authors failed to meet this goal? With a significance level of 0.05, test an appropriate hypothesis and state your conclusion.

- CASE STUDY: #2 In August 2000, a young woman from Gozo, an island south of Italy, discovered that she was carrying conjoined twins. Knowing that health-care facilities on Gozo were inadequate to deal with the complications of such a birth, she and her husband went to St. Mary’s Hospital in Manchester, England, to have the babies delivered. The infants, known as Mary and Jodie, were joined at the lower abdomen. Their spines were fused, and they had one heart and one pair of lungs between them. Jodie, the stronger one, was providing blood for her sister. No one knows how many sets of conjoined twins are born each year, but the number has been estimated at 200. Most die shortly after birth, but some conjoined twins do well. They grow to adulthood and marry and have children themselves. But the outlook for Mary and Jodie was grim. The doctors said that without intervention the girls would die within six months. The only hope was an operation to separate them. This would save Jodie, but…arrow_forwardPls answer the both question, they are related with each other.arrow_forwardA company is considering an organizational change which entails adopting the use of self-managed work teams which they hope will lead to higher levels of employee satisfaction.

Destructive testing was conducted in some of these units as a result of the responses. Based on the tests, the owners' association inferred the damage over the entire condo complex. Do you think that the inference is valid in this case? a). No, the inference is not valid. It is an example of sample selection bias because owners whose units were relatively more damaged were more likely to make theor units available for destructive testing. b).
