Can I please have an explanation on how to do these? Thank you!

I) Complete each statement below. Select the appropriate choice from each dropdown menu to make the statement true. When the sample size is large, the mean of the sample means (p.53) is [Select] V the mean of X. When the sample size is large, the standard deviation of the sample means (053) is [Select] V the standard deviation of X. less than approximately equal to greater than 2) If x represents a random variable with mean 235 and standard deviation 51.7. Find the standard deviation of the sampling distribution of the means with sample size 46. Express the answer as a decimal value rounded to the nearest hundredth. 3) Blood pressure reading is determined by measuring systolic and diastolic blood pressures. Systolic blood pressure, the top number, measures the force the heart exerts on the walls of the arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force the heart exerts on the walls of the arteries in between beats. Suppose the systolic blood pressure readings have a mean of 116 millimeters of mercury (mmHg) and a standard deviation of 12.2 mmHg. If 35 people are randomly selected and the mean of their systolic pressure reading is 114, nd the z-score associated with that sample mean. Express the answer as a decimal value rounded to the nearest thousandth. '0 7) As of 2021, the distribution of salaries for high school teachers in California is approximately normal with a mean of $70,079 and a standard deviation of $16,316. If 20 high school teachers in California are randomly selected, nd the probability the mean salary of those teachers is higher than $70,000. Express the answer as a decimal value rounded to the nearest thousandth. Blood pressure reading is determined by measuring systolic and diastolic blood pressures. Systolic blood pressure, the top number, measures the force the heart exerts on the walls of the arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force the heart exerts on the walls of the arteries in between beats. Suppose the diastolic blood pressure readings have a mean of 74 millimeters of mercury (mmHg) and a standard deviation of 5 mmHg. If 44 people are randomly selected, nd the probability their mean diastolic pressure reading is between 70 and 73 mmHg. Express the answer as a decimal value rounded to the nearest thousandth. As of 2021, the distribution of salaries for nurse practitioners in the United States of America is approximately normal with a mean of $112,668 and a standard deviation of $14,421. if 50 nurse practitioners are randomly selected, nd the 80th percentile mean salary. Round the answer to the nearest whole number. The distribution of weights of pumpkins from a harvest is approximately normal with a mean of 8.3 pounds and a standard deviation of 1.51 pounds. Find the value of the interquartile range (IQR) for the mean of 15 pumpkins. Express the answer as a decimal value rounded to the nearest thousandth
