At what ages are school children screened for vision problems.
At what age(s) are schoolchildren screened for hearing problems
It is generally believed that nearsightedness affects about 15% of children. A school district gives vision tests to 111 incoming kindergarten children. Use the empirical rule (68%-95%-99.7% Rule) to determine what proportion of nearsighted children we might expect to see in samples of 111 children (I'm not looking for the number of children). Assume conditions are met! Based on your results, would you be surprised to find a sample where 20% of children were nearsighted? Find the z-score and resulting probability to...
It is generally believed that nearsightedness affects about 15% of children. A school district gives vision tests to 111 incoming kindergarten children. In our sample of 111 students, we find 13% of the students were nearsighted. Construct a 90% confidence interval for the number of nearsighted kindergarteners we would expect to see based on our sample. Does this support or refute the estimate of 15%? Assume conditions are met (so don't check them)! Explain in details
Epidemiology question 1.The Oakland Nutrition Program enrolled 500 children in January 2012. All of these children were screened for obesity at the beginning of the year and 66 were found to have overweight problems. When the same 500 children are screened again in January 2013, 80 are found to have overweight problems. What is the risk of developing overweight problems over the period of time between the January of 2012 and January of 2013 in this group of Nutrition Program...
State law requires that all children between the ages of 5 and 16 years attend an approved school. Defendants have been charged with violating the statute, as they do not permit their children to attend school. The defendants are Mennonites and claim that it would violate their First Amendment right to freely exercise their religion. The defendants teach their children in a manner consistent with their religious teachings. Should they be convicted?
A newly divorced mother moves with her three children ages 4,7 and 15, into a new neighborhood. What interventions could a school nurse or health care worker use to help the family make a health adjustment to their new life?
Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.8 years with a standard deviation of 1.1 years. Step 1 of 2: If a sampling distribution is created using samples of the ages at which 65 children begin reading, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary. Step 2 of 2:If a sampling distribution is created using samples of...
How can pushing children to write too early hinder their fine motor development? What problems can these children have once they enter public school?
Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.4 years with a standard deviation of 0.8 years. Step 1 of 2 : If a sampling distribution is created using samples of the ages at which 38 children begin reading, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.
Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.7 years with a standard deviation of 0.7 years. Step 1 of 2: If a sampling distribution is created using samples of the ages at which 55 children begin reading, what would be the mean of the sampling distribution of sample means?
