Volunteers who had developed a cold within the previous 24 hours were randomized to take either zinc or placebo lozenges every 2 to 3 hours until their cold symptoms were gone. Twenty-five participants took zinc lozenges, and 23 participants took placebo lozenges. The mean overall duration of symptoms for the zinc lozenge group was 4.5 days, and the standard deviation of overall duration of symptoms was 1.4 days. For the placebo group, the mean overall duration of symptoms was 7.8 days, and the standard deviation was 2 days.

the size of the left upper chamber or the heart is one measure or cardiovascular health. the paper “ left atrial size increases with body mass index in children “ international journal of cardiology [ 2009 ] : 1-7) described a study in which the left atrial size was measured for a large number of children of age 5 to 15 years. based on this data the authors concluded that for healthy children, left atrial diameter was approximately normally distributed with a mean of 26.4 mm and a standard deviation of 4.2 mm. round all answers to four decimal places a. what is the probability that a randomly selected healthy child will have a left atrial diameter less than 24mm? round to 4 decimal places b. what is the probability that a randomly selected healthy child will have a left atrial donated greater than 32 mm? round to 4 decimal places c. what is the probability that a randomly selected healthy child will have a left atrial diameter between 25 and 30mm? round to 4 decimal places.

Facebook: A study showed that two years ago, the mean time spent per visit to Facebook was 20.8 minutes, Assume the standard devlation is o= 8.0 minutes. Suppose that a simple random sample of 107 visits was selected this year and has a sample mean of x= 18.8 minutes. A social scientist is interested to know whether the mean time of Facebook visits has decreased. Use the a=0.10 level of significance and the critical value method with the table. (a) State the appropriate null and alternate hypotheses. (b) Compute the value of the test statistic. (c) State a conclusion. Use the a = 0.10 level of significance.
Green Sea Urchins. From the paper “Effects of Chronic Nitrate Exposure on Gonad Growth in Green Sea Urchin Strongylocentrotus droebachiensis” (Aquaculture, Vol. 242, No. 1–4, pp. 357– 363) by S. Siikavuopio et al., we found that weights of adult green sea urchins are normally distributed with mean 52.0 g and standard deviation 17.2 g. a. Find the percentage of adult green sea urchins with weights between 50 g and 60 g. b. Obtain the percentage of adult green sea urchins with weights above 40 g. c. Determine and interpret the 90th percentile for the weights. d. Find and interpret the 6th decile for the weights.
