Answer:
a) T test
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Step-by-step explanation:
Construction of hypothesis
H₀ : p = 75
H₁ : p ≠ 75
Here Standard deviation = 7
sample = n = 50
Average = x-bar = 78
Level of significance:
∝ = 5% = 0.05
Degree of freedom:
df = n-1
= 50 -1 = 49
Critical value :
± 1.96
a) T test
test t is used as average X mean is used
Test Statistic:
t = X₂ - X₁ / Sd /√n
= 78 - 75 / 7/√50
=3.0304
Critical region :
We take two tail T test
test statistic is in reject interval. Reject H₀
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
A) the Johnson family will travel 300 miles in 5 hours
Assuming 5, represents the amount of hours & 300 representing miles
4/3 (k)(k + 7)(3k + 9)
4/3 (k)(3k^2 + 9k + 21k + 63)
4/3 (k)(3k^2 + 30k + 63)
4/3 (3k^3 +30k + 63)
4k^3 +40k +84

Answer:
7.2
Step-by-step explanation:
Given:
Fabian Harvey says 10 pounds of tomatoes from his garden
He sets aside 2.8 pounds of tomatoes to make spaghetti sauce
Question asked:
How many batches of soup can Fabian make ?
Solution:
By subtracting:
Total pounds of tomatoes = 10
He sets aside = 2.8
Remaining pounds of tomatoes = 10 - 2.8 = 7.2 pounds of tomatoes
Thus, 7.2 pounds of tomatoes of batches of soup Fabian can make.
