Answer:
Due to the higher z-score, David has the higher standardized score
Step-by-step explanation:
Z-score:
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Which student has the higher standardized score
Whoever had the higher z-score.
David:
Scores on Ms. Bond's test have a mean of 70 and a standard deviation of 11. David has a score of 52 on Ms. Bond's test. So 



Steven:
Scores on Ms. Nash's test have a mean of 64 and a standard deviation of 6. Steven has a score of 52 on Ms. So 



Due to the higher z-score, David has the higher standardized score
Answer:
The standard error is 0.02849
Step-by-step explanation:
<u>Explanation:</u>-
given data is 42% of primary case doctors think their patients receive un-necessary medical care.
That is The proportion 'p' = 42% = 0.42
Given sample size is n =300
The standard error of the sampling distribution of the sample proportion is


use calculator on simplification , we get
standard error = 0.02849
Answer:
See below
Step-by-step explanation:
BC bisects <DBE and if AC is a straight line then you have that:
<ABD + <DBC = 180 (straight angle because of line AC)
<ABE + <CBE = 180 ( straight angle because of line AC)
Because BC bisects <DBE => < DBC = <CBE
So <ABD and <ABE must be the same to both sum 180 when added < DBC
Answer:
c = 34/d
d = 1/2
Step-by-step explanation:
Part A
Basic Formula
c = k/d
17 = k/2 Multiply both sides by 2
17*2 = k*2/2 Combine
34 = k
So the equation is c = 34/d
Part B
c = 68
k = 34
d = ?
68 = 34/d Multiply both sides by d
68*d = 34 * d/d Simplify.
68 d = 34 Divide by 68
d = 34/68 Simplify
d = 1/2
Answer:
Step-by-step explanation:
Just divide the larger mass by the smaller.
0.5 / 0.005 = 0.5 / 0.5 * 10^-2 = 1 * 10^2 = 100
It take 100 ants to equal the mass of a grasshopper.
