An agricultural researcher is interested in estimating the mean length of the growing season in a region. Treating the last 10 years as a simple random sample, he obtains the following data, which represent the number of days of the growing season. What is the point estimate of the population mean number of days of the growing season?
151
159
148
147
163
187
195
184
169
149
The point estimate is __.

Solution :
n =
= 
= (151 + 159 + 148 + 147 + 163 + 187 + 195+ 184 + 169 + 149) / 10
= 165.2

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...

Question 8 A researcher is interested in estimating the effect that the number of cigarettes that a pregnant mother smokes has on her baby's health. A common measure of a child's health and birth is her weight regression: The researcher decides to estimate the following where Wi the weight at birth of mother i's baby (in pounds) the daily number of cigarettes smoked by mother i during the pregnancy 1. Would you expect the estimate of 0, to be positive...

Suppose that a researcher is interested in estimating the mean systolic blood pressure, u, of executives of major corporations. He plans to use the blood pressures of a random sample of executives of major corporations to estimate u. Assuming that the standard deviation of the population of systolic blood pressures of executives of major corporations is 25 mm Hg, what is the minimum sample size needed for the researcher to be 90% confident that his estimate is within 3 mm...

Assume we are interested in the following events: this is everything that was given A: DCL > 260mm, B: TL > 180cm. Use the data and the concept of probability as a relative frequency to estimate the probabilities (relative frequencies) of these two events and of the joint event: A and B. Are A and B independent events? P(A) = P(B) = P(A and B) = Is this most accurately categorized as an observational or experimental study?...
