Twenty years ago, 52% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 214 of 700 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a = 0.05 level of significance. Because npo (1- Po) = V 10, the sample size is V 5% of the population size, and the sample V the requirements for testing the hypothesis V satisfied. (Round to one decimal place as needed.)

**Statistical Analysis of Parental Concerns Over Math and Science Education**
Twenty years ago, 52% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 214 out of 700 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the α = 0.05 level of significance.
To determine if there is a statistically significant difference:
1. **Condition for Sample Size Adequacy:**
\[
np_0 (1 - p_0) = \boxed{\phantom{x}}
\]
If this value is greater than or equal to 10, the sample size is appropriate.
2. **Percentage Check:**
Ensure the sample size is at least 5% of the population size.
3. **Hypothesis Testing:**
Determine if the requirements for testing the hypothesis are \(\boxed{\text{Satisfied/Not Satisfied}}\).
**Note:** Please round all calculations to one decimal place as needed.
This exercise is intended to guide you through the process of hypothesis testing using real-world data, ensuring a thorough understanding of statistical significance in parental perceptions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F69bfa557-4209-42ee-b04b-950601280336%2Fc79b9d8b-bef0-48b5-b82e-1b76a03e2a67%2Fhksi8s9_processed.png&w=3840&q=75)
