(b) Suppose samples of size n = 100 are selected from a population with mean 80 and standard deviation 8. State the mean, standard error, and distribution of the sampling distribution of the sample mean. (iii) The shape of the distribution:0.948
(c) Suppose samples of size n = 16 are selected from a population that is approximately normal with mean 80 and standard deviation 8. State the mean, standard error, and distribution of the sampling distribution of the sample mean. Suppose that, over a certain period of time, a parent monitors how many texts their 17 year old son sends each day. The average amount of texts sent a day is 42, and the standard deviation is 12.(a) If one day from this time period is randomly selected, and the number of texts for that day is one standard deviation above the population mean, how many texts were sent that day?(whole number)(b) What is the mean of the sampling distribution of the sample mean?
