Tay-Sachs is a recessive disease that causes nerve cells to malfunction and results in death by age 4. Two healthy parents know from blood tests that each parent carries a recessive allele responsible for Tay-Sachs. If their first 3 children have the disease what is the probability that their 4th will have the diseas?
Answers
Tay-Sachs is a genetic disease that causes malfunctioning of nerve cells, leading to death by age 4. It is caused by the recessive allele, and there is a 25% that the fourth child will be affected by the disease.
In the given scenario, both parents carry a recessive allele responsible for Tay-Sachs.
The probability of passing the recessive allele from each parent to the child is 1/2.
The probability of having a child with Tay-Sachs disease is the product of the probability of receiving the recessive allele from both parents.
Each child inherits one allele from each parent. If both alleles received are recessive, the child will have Tay-Sachs disease.
Therefore, the probability of having a child with Tay-Sachs is 1/2 × 1/2 = 1/4.
The probability of having a child with Tay-Sachs in this family is 1/4.
Thus, there is a 25% chance that their fourth child will be affected by the disease.

Answers
1. Population parameter: In the given example, the population parameter refers to a characteristic or value related to the entire population of older adults with obesity. It could be the average LDL cholesterol level in this population.
2. Sample statistic: A sample statistic is a measure or characteristic calculated from a sample taken from the population. In this case, it could be the average LDL cholesterol level observed in each group of 15 participants after implementing the DASH diet.
3. Sampling error: Sampling error refers to the discrepancy or difference between the sample statistic and the population parameter. It occurs due to the inherent variability between individuals in the population and the limited sample size. It represents the uncertainty in estimating the population parameter based on a sample.
4. Standard error: The standard error is a measure of the variability or precision of the sample statistic. It quantifies the expected deviation between the sample statistic and the population parameter. It is calculated using the sample data and provides an estimate of the variability between different samples from the same population.
In this study, the population parameter would be the average LDL cholesterol level in the entire population of older adults with obesity. However, it is not feasible to measure the cholesterol level in every individual in the population. Hence, a sample of 30 individuals (15 per group) is selected.
The sample statistic would be the average LDL cholesterol level observed in each group after implementing the DASH diet. This statistic is calculated from the sample data and provides an estimate of the population parameter.
Sampling error refers to the discrepancy between the sample statistic and the population parameter. It arises because the sample is only a subset of the entire population, and different samples may yield different results. The sampling error quantifies the uncertainty in generalizing the sample statistic to the entire population.
The standard error is a measure of the variability or precision of the sample statistic. It indicates how much the sample statistic is expected to deviate from the population parameter due to random sampling. A smaller standard error indicates a more precise estimate of the population parameter. It is calculated using the sample data and provides valuable information for the interpretation and generalization of the results.

Manuel’s doctor is concerned with his blood pressure readings. What is MOST likely to be concerning about Manuel’s results? A. His systolic blood pressure is higher than 80. B. His diastolic blood pressure is 120. C. His blood pressure is 115/75. D. His systolic blood pressure is less than 100.
Answers
It is essential to monitor and regulate one's blood pressure to maintain a healthy body and lifestyle. If a patient's blood pressure is consistently high, a doctor may recommend lifestyle changes, medication, or a combination of both to lower their blood pressure.
Manuel's doctor is concerned about his blood pressure readings. A blood pressure reading consists of two numbers: systolic and diastolic blood pressure. The systolic pressure is the higher number that measures the pressure in the arteries when the heart muscle contracts.
The diastolic pressure is the lower number that measures the pressure in the arteries between heartbeats. Blood pressure is determined by a variety of factors, including the amount of blood the heart pumps, the resistance of the blood vessels to blood flow, and the volume of blood in the circulatory system. When there is a problem with any of these factors, the blood pressure can increase, leading to various health issues.
In this case, the answer is B. His diastolic blood pressure is 120. Manuel's diastolic blood pressure is dangerously high, which is cause for concern. A normal blood pressure reading is typically less than 120/80 mm Hg, with the diastolic pressure less than 80.
A reading of 120/80 mm Hg or higher is considered prehypertension, which can increase the risk of developing hypertension or high blood pressure. High blood pressure can lead to a variety of health problems, including heart disease, stroke, kidney disease, and even death.
