Answer:
The estimate is
Step-by-step explanation:
From the question we are told that
The sample mean is 
The sample size is n = 24
The standard deviation is 
Given that the confidence level is 90% the level of significance is mathematically represented as
Next we obtain the critical value of 
from the normal distribution table.The value is
The reason we are obtaining critical value of instead of 
is because
represents the area under the normal curve where the confidence level interval ( 
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
NOTE: We can also obtain the value using critical value calculator (math dot armstrong dot edu)
Generally the margin of error is mathematically represented as
substituting values
The estimate of how much the drug will lower a typical patient's systolic blood pressure(using a 90% confidence level) is mathematically represented as
substituting values
Option D is correct. The correct statement that represents the graph is R: {y E R | y ≥ -3}
From the given graph, we are to get the range.
The range is the output value for which the function of the graph exists. The required output values are the y-values.
From the graph shown, we can see that the range of y is from -3 to 1. This can be denoted as;
Range = [-3, 1)
This shows that the range of the graph are all the values greater than -3 including -3.
The correct statement will therefore be;
R: {y E R | y ≥ -3}

Answer:
1/32
Step-by-step explanation:
Since we want to find the probability that all five coins land on heads, we must first find the total number of possibilities. Since there are 2 choices for each coin to land on, heads or tails, the total number of possibilities is 2^5 = 32.
Since there is only one way to to land on all heads, the probability is 1/32.
