The director of a shipping company believes that there is a relationship between the cost of a customer’s shipment (£) and the weight (lb) of the package being shipped. For investigating this possible relationship, a random sample of nine customer shipments was selected and the weight (in lb) and the cost (rounded to the nearest £) for each shipment were recorded. The results obtained are shown in the table below (on the picture). required: a) ) The scatter diagram showing the relationship between the cost of acustomer’s shipment (£) and the weight (lb) of the package being shipped, is given below. Comment fully and clearly on this diagram. i) ii)

A data with 18 points will be integrated as accurately as possible using a combination of Simpson's rules. It will require ____ applications of Simpson's 3/8th rule and _____ applications of Simpson's 1/3rd rule
Suppose a researcher is interested in the relationship between periodontal disease and a number of negative health outcomes. One outcome of particular interest to the researcher is hypertension (assume defined as systolic blood pressure above 140 mmHG). Suppose a team gathers a SRS of 348 participants with periodontal disease, and finds the sample average systolic blood pressure to be 157 mmHG. A) Using an assumed σ=16 mmHG, conduct a 1 sample Z test to determine if there is a relationship between periodontal disease and hypertension in this population. (Use α=0.05)

A random sample of senior citizens living in a retirement village reported that they had an average of 1.42 face-to-face interactions per day with their neighbors. A random sample of those living in age-integrated communities reported 1.58 interactions per day. Is the difference between the two senior citizen groups significant? Please provide t critical, t obtained and your decision. Retirement Community 1 Retirement Community 2 Mean1 = 1.42 Mean2 = 1.58 s1 = 0.10 s2 = 0.78 N1 = 43 N2 = 37
