Answer:
Pam missed 32 words in her pretest.
It will take 4 days for Pam to learn all missed words.
Step-by-step explanation:
Given:
Number of words spelled correctly = 68
Total number of words on the pretest = 100
We need to find the number of words she missed.
Solution:
now we can say that;
Number of words she missed can be calculated by subtracting Number of words spelled correctly from Total number of words on the pretest.
framing in equation form we get;
Number of words she missed =
Hence Pam missed 32 words in her pretest.
Now Given:
Number of words missed learned each day = 8
Total number of words missed = 32 words.
We need to find how long will take to learn them all.
now we can say that;
days required to learn missed words is equal to total number of words missed divided by Number of words missed learned each day.
framing in equation form we get;
Days required to learn missed words =
Hence It will take 4 days for Pam to learn all missed words.
Answer:
p = 0.0116
Step-by-step explanation:
We are given;
Population mean; μ = 200 mg
Sample mean; x¯ = 194.3 mg
Standard deviation; σ = 21 mg
Sample size; n = 70
Formula for z-score is;
z = (x¯ - μ)/(σ/(√n))
z = (194.3 - 200)/(21/√70)
z = -5.7/2.51
z = -2.27
From the z-score table attached, the p-value at z = -2.27 is p = 0.0116
