Module 4 Assignment: Analyzing Car CO₂ Emissions

[Dut_Manut_Ayiei_Dut]

this code is generating error. can someone help me correct this code please? # 1. Filter the data
compact = df[df[‘Vehicle class’] == ‘Compact’]
mid_size = df[df[‘Vehicle class’] == ‘Mid-size’]

2. Perform the two-sample t-test (Welch’s)

t_stat, p_value = stats.ttest_ind(
compact[‘CO2 emissions’],
mid_size[‘CO2 emissions’],
equal_var=False,
alternative=‘two-sided’ # adjust to ‘greater’ or ‘less’ if needed
)

Hi @Dut_Manut_Ayiei_Dut

The issue with your code is due to the use of invalid quotation marks (‘ and ’) (a bit curved shape) instead of regular Python string quotes (' or ") (straight lines).

Hope it helps!
